| Custom Control Group Resources (overrides Cgroup settings) | Custom control group resources to assign to this role, which will be enforced by the Linux kernel. These resources should exist on the target hosts, otherwise an error will occur when the process starts. Use the same format as used for arguments to the cgexec command: resource1,resource2:path1 or resource3:path2 For example: 'cpu,memory:my/path blkio:my2/path2' ***These settings override other cgroup settings.*** |

| Cgroup I/O Weight | Weight for the read I/O requests issued by this role. The greater the weight, the higher the priority of the requests when the host experiences I/O contention. Must be between 100 and 1000. Defaults to 1000 for processes not managed by Cloudera Manager. |

| Cgroup Memory Hard Limit | Hard memory limit to assign to this role, enforced by the Linux kernel. When the limit is reached, the kernel will reclaim pages charged to the process. If reclaiming fails, the kernel may kill the process. Both anonymous as well as page cache pages contribute to the limit. Use a value of -1 to specify no limit. By default processes not managed by Cloudera Manager will have no limit. If the value is -1, Cloudera Manager will not monitor Cgroup memory usage therefore some of the charts will show 'No Data' |

-1 MiB |
rm_memory_hard_limit
|
true |
| Cgroup Memory Soft Limit | Soft memory limit to assign to this role, enforced by the Linux kernel. When the limit is reached, the kernel will reclaim pages charged to the process if and only if the host is facing memory pressure. If reclaiming fails, the kernel may kill the process. Both anonymous as well as page cache pages contribute to the limit. Use a value of -1 to specify no limit. By default processes not managed by Cloudera Manager will have no limit. If the value is -1, Cloudera Manager will not monitor Cgroup memory usage therefore some of the charts will show 'No Data' |
