DataNode Data Directory | Comma-delimited list of directories on the local file system where the DataNode stores HDFS block data. Typical values are /data/N/dfs/dn for N = 1, 2, 3.... In CDH 5.7 and higher, these directories can be optionally tagged with their storage types, for example, [SSD]/data/1/dns/dn. HDFS supports the following storage types: [DISK], [SSD], [ARCHIVE], [RAM_DISK]. The default storage type of a directory will be [DISK] if it does not have a storage type tagged explicitly. These directories should be mounted using the noatime option, and the disks should be configured using JBOD. RAID is not recommended. Warning: Be very careful when modifying this property. Removing or changing entries can result in data loss. To hot swap drives in CDH 5.4 and higher, override the value of this property for the specific DataNode role instance that has the drive to be hot-swapped; do not modify the property value in the role group. See Configuring Hot Swap for DataNodes for more information. | dfs.datanode.data.dir | dfs_data_dir_list | true | |
Reserved Space for Non DFS Use | Reserved space in bytes per volume for non Distributed File System (DFS) use. | dfs.datanode.du.reserved | 10 GiB | dfs_datanode_du_reserved | false |

---|---|---|---|---|---|
DataNode Balancing Bandwidth | Maximum amount of bandwidth that each DataNode can use for balancing. Specified in bytes per second. | dfs.datanode.balance.bandwidthPerSec | 10 MiB | dfs_balance_bandwidthPerSec | false |
Enable purging cache after reads | In some workloads, the data read from HDFS is known to be significantly large enough that it is unlikely to be useful to cache it in the operating system buffer cache. In this case, the DataNode may be configured to automatically purge all data from the buffer cache after it is delivered to the client. This may improve performance for some workloads by freeing buffer cache spare usage for more cacheable data. This behavior will always be disabled for workloads that read only short sections of a block (e.g HBase random-IO workloads). This property is supported in CDH3u3 or later deployments. | dfs.datanode.drop.cache.behind.reads | false | dfs_datanode_drop_cache_behind_reads | false |
Enable purging cache after writes | In some workloads, the data written to HDFS is known to be significantly large enough that it is unlikely to be useful to cache it in the operating system buffer cache. In this case, the DataNode may be configured to automatically purge all data from the buffer cache after it is written to disk. This may improve performance for some workloads by freeing buffer cache spare usage for more cacheable data. This property is supported in CDH3u3 or later deployments. | dfs.datanode.drop.cache.behind.writes | false | dfs_datanode_drop_cache_behind_writes | false |
Handler Count | The number of server threads for the DataNode. | dfs.datanode.handler.count | 3 | dfs_datanode_handler_count | false |
Maximum Number of Transfer Threads | Specifies the maximum number of threads to use for transferring data in and out of the DataNode. | dfs.datanode.max.transfer.threads | 4096 | dfs_datanode_max_xcievers | false |
Number of read ahead bytes | While reading block files, the DataNode can use the posix_fadvise system call to explicitly page data into the operating system buffer cache ahead of the current reader's position. This can improve performance especially when disks are highly contended. This configuration specifies the number of bytes ahead of the current read position which the DataNode will attempt to read ahead. A value of 0 disables this feature. This property is supported in CDH3u3 or later deployments. | dfs.datanode.readahead.bytes | 4 MiB | dfs_datanode_readahead_bytes | false |
Enable immediate enqueuing of data to disk after writes | If this configuration is enabled, the DataNode will instruct the operating system to enqueue all written data to the disk immediately after it is written. This differs from the usual OS policy which may wait for up to 30 seconds before triggering writeback. This may improve performance for some workloads by smoothing the IO profile for data written to disk. This property is supported in CDH3u3 or later deployments. | dfs.datanode.sync.behind.writes | false | dfs_datanode_sync_behind_writes | false |
HDFS Thrift Server Max Threadcount | Maximum number of running threads for the HDFS Thrift server running on each DataNode | dfs.thrift.threads.max | 20 | dfs_thrift_threads_max | false |

Temporary Dump Directory | NFS clients often reorder writes. As a result, sequential writes can arrive at the NFS Gateway in random order. This directory is used to temporarily save out-of-order writes before writing to HDFS. For each file, the out-of-order writes are dumped after they are accumulated to exceed certain threshold (e.g., 1MB) in memory. Please make sure this directory has enough space. For example, if the application uploads 10 files with each having 100MB, it is recommended that this directory have roughly 1GB of space in case write reorder happens (in the worst case) to every file. | dfs.nfs3.dump.dir | /tmp/.hdfs-nfs | dfs_nfs3_dump_dir | false |
Allowed Hosts and Privileges | By default, NFS Gateway exported directories can be mounted by any client. For better access control, update this property with a list of host names and access privileges separated by whitespace characters. Host name format can be a single host, a Java regular expression, or an IPv4 address. The access privilege uses rw to specify readwrite and ro to specify readonly access. If the access privilege is not provided, the default is read-only. Examples of host name format and access privilege: "192.168.0.0/22 rw", "host.*.example.com", "host1.test.org ro". | dfs.nfs.exports.allowed.hosts | * rw | dfs_nfs_exports_allowed_hosts | false |

Enable Audit Collection | Enable collection of audit events from the service's roles. | navigator.audit.enabled | true | navigator_audit_enabled | false |
Audit Event Filter | Event filters are defined in a JSON object like the following: { "defaultAction" : ("accept", "discard"),
"rules" : [ { "action" : ("accept", "discard"), "fields" : [ { "name" : "fieldName", "match" : "regex" } ] } ] } A filter has a default action and a list of rules, in order of precedence. Each
rule defines an action, and a list of fields to match against the audit event. A rule is "accepted" if all the listed field entries match the audit event. At that point, the action declared by the
rule is taken. If no rules match the event, the default action is taken. Actions default to "accept" if not defined in the JSON object. The following is the list of fields that can be filtered for
HDFS events:

first appear, and comparing other incoming events against the "tracked" events according to the rules defined here. Event trackers are defined in a JSON object like the following: { "timeToLive" : [integer], "fields" : [ { "type" : [string], "name" : [string] } ] } Where:

Click + to add a new redaction rule. You can choose one of the preconfigured rules or add a custom rule. When specifying a custom rule, the Search field should contain a regular expression that will be matched against the data. If a match is found, it is replaced by the contents of the Replace field.Trigger is an optional field. It can be used to specify a simple string to be searched in the data. If the string is found, the redactor attempts to find a match for the Search regex. If no trigger is specified, redaction occurs by matching the Search regular expression. Use the Trigger field to enhance performance: simple string matching is faster than regular expression matching.Test your rules by entering sample text into the Test Redaction Rules text box and clicking Test Redaction. If no rules match, the text you entered is returned unchanged. | redaction_policy | redaction_policy | false | |
