> Key: HDDS-3927
> URL: https://issues.apache.org/jira/browse/HDDS-3927

> Issue Type: Improvement
> Reporter: Siyao Meng
> Assignee: Siyao Meng
> Priority: Minor
> Labels: pull-request-available
> Fix For: 1.1.0
>
>
> Similar to {{HDFS_NAMENODE_OPTS}}, {{HDFS_DATANODE_OPTS}}, etc., we should
> have {{OZONE_MANAGER_OPTS}}, {{OZONE_DATANODE_OPTS}} to allow adding JVM args
> for GC tuning and debugging.
> Update 1:
> [~bharat] mentioned we already have some equivalents for OM and Ozone DNs:
> -
> [HDFS_OM_OPTS|https://github.com/apache/hadoop-ozone/blob/bc7786a2fafb2d36923506f8de6c25fcfd26d55b/hadoop-ozone/dist/src/shell/ozone/ozone#L157]
> for Ozone OM. This looks like a typo, should begin with HDDS
> -
> [HDDS_DN_OPTS|https://github.com/apache/hadoop-ozone/blob/bc7786a2fafb2d36923506f8de6c25fcfd26d55b/hadoop-ozone/dist/src/shell/ozone/ozone#L108]
> for Ozone DNs
> Update 2:
> - HDFS_OM_OPTS -> OZONE_OM_OPTS
> - HDDS_DN_OPTS -> OZONE_DATANODE_OPTS
> - HDFS_STORAGECONTAINERMANAGER_OPTS -> OZONE_SCM_OPTS
> The new names conforms to {{hadoop_subcommand_opts}}. Thanks [~elek] for
> pointing this out.
> Objective:
> Rename the environment variables to be in accordance with the convention, and
> keep the compatibility by deprecating the old variable names.
