Settings and Cluster Configuration

Ambari configures Hive View settings automatically when you choose to add the Hive service. The default Hive View settings are shown in the following figure:

Figure 9.1. Default Hive View Settings

The default Hive View cluster configuration is shown in the following figure:

Figure 9.2. Default Hive View Cluster Configuration

If required for migrating view instances, the following table describes how to locate cluster configuration settings using Ambari.

Table 9.2. Finding Cluster Configuration Values for the Hive View using Ambari

Property	Value
HiveServer2 JDBC URL For secured clusters, see Kerberos Setup for Hive Views	Click Hive > Summary to view the URL, diplayed at the bottom of the Summary list. For example: `jdbc:hive2://c6403.ambari.apache.org:2181,c6401.ambari.apache.org:2181,c6402.ambari.apache.org:2181/;serviceDiscoveryMode=zooKeeper;zooKeeperNamespace=hiveserver2`
Hive Metastore directory	Click Hive > Configs > Advanced > General. For example, `/apps/hive/warehouse`
WebHDFS FileSystem URI*	Click HDFS > Configs > Advanced >Advanced hdfs-site For example `dfs.nameserviceid.http-address`
WebHDFS FileSystem URI*	For HA: Click HDFS > Configs > Advanced > Advanced hdfs-site > dfs.nameservice.id. When you enter the value in the view definition, pre-pend "webhdfs://" to the value you find in the advanced HDFS configuration settings. For example, `webhdfs://c6401.ambari.apache.org:50070 or webhdfs://nameserviceid`
Logical Name of the NameNode cluster
List of NameNodes
First NameNode RPC Address	Click HDFS > Configs > Advanced > Advanced hdfs-site > dfs.namenode.rpc-address. See the first address in the list. For example, `c6401.ambari.apache.org`
Second NameNode RPC Address	Click HDFS > Configs > Advanced > Advanced hdfs-site > dfs.namenode.rpc-address. See the second address in the list. For example, `c6402.ambari.apache.org`
First NameNode HTTP (WebHDFS) Address	Click HDFS > Configs > Advanced > Advanced hdfs-site > dfs.namenode.http-address See the first address in the list. For example, `c6401.ambari.apache.org`
Second NameNode HTTP (WebHDFS) Address	Click HDFS > Configs > Advanced > Advanced hdfs-site > dfs.namenode.http-address See the second address in the list. For example, `c6402.ambari.apache.org`
First NameNode HTTPS (WebHDFS) Address	Click HDFS > Configs > Advanced > Advanced hdfs-site > dfs.namenode.https-address See the first address in the list. For example, `c6401.ambari.apache.org`
Second NameNode HTTPS (WebHDFS) Address	Click HDFS > Configs > Advanced > Advanced hdfs-site > dfs.namenode.https-address See the second address in the list. For example, `c6402.ambari.apache.org`
Failover Proxy Provider	Click HDFS > Configs > Advanced > Advanced hdfs-site > dfs.client.failover.proxy.provider[nameservice]
Umask	Click HDFS > Configs > Advanced > Advanced hdfs-site > fs.permissions.umask-mode The default value is 022. Do not change this value unless you are sure that you understand the effects of changing the value on your Hive View cluster. The umask property defines the file mode creation mask, which controls how file permissions are configured in new files.
Auth To Local	Click HDFS > Configs > Advanced > Advanced core-site > hadoop.security.auth_to_local
YARN Application Timeline Server URL*	Click YARN > Configs > Advanced > Application Timeline Server > yarn.timeline-service.webapp.address. When you enter the value in the view definition, pre-pend "http://" to the value you find in the YARN advanced configuration settings. For example, `http://c6401.ambari.apache.org:8188`
YARN ResourceManager URL*	Click YARN > Configs > Advanced > Advanced yarn-site > yarn.resourcemanager.webapp.address. When you enter the value in the view definition, pre-pend "http://" to the value you find in the YARN advanced configuration settings. For example, `http://c6401.ambari.apache.org:8088`

For NameNode High Availability

The following values must be entered for primary and secondary NameNodes:

Table 9.3. Hive View Settings for NameNode High Availability

Property	Value
First NameNode RPC Address or Second NameNode RPC Address	Select the primary or secondary NameNode to view settings from that host in the cluster. See how to get the NameNode RPC address. When you enter the value in the view definition, pre-pend "http://" to the value you find in the advanced `hdfs-site` settings. For example, `http://c6401.ambari.apache.org:8020`
First NameNode HTTP (WebHDFS) Address or Second NameNode HTTP (WebHDFS) Address	Click HDFS > Configs > Advanced > Advanced hdfs-site > dfs.namenode.http-address. When you enter the value in the view definition, pre-pend "http://" to the value you find in the advanced `hdfs-site` settings. For example, `http://c6401.ambari.apache.org:50070`

To get First NameNode RPC Address values:

Navigate to the HDFS service page in Ambari that contains links to individual NameNodes. Click NameNode (primary) or SNameNode (secondary) to view the host page:

Figure 9.3. HDFS Service Page in Ambari
On the host page, click Configs > Advanced.
Enter "rpc" in the Filter search well at the top right corner of the page or navigate to the Advanced hdfs-site settings to find the dfs.namenode.rpc-address value that you can enter into the Hive View definition. Here is an example of using the Filter to locate a value:
