> [HOD] No way to set HADOOP_OPTS environment variable to the Hadoop daemons
> through HOD
> --------------------------------------------------------------------------------------
>
> Key: HADOOP-2766
> URL: https://issues.apache.org/jira/browse/HADOOP-2766
> Project: Hadoop Core
> Issue Type: Bug
> Components: contrib/hod
> Affects Versions: 0.16.0, 0.16.1, 0.17.0
> Reporter: Hemanth Yamijala
> Assignee: Vinod Kumar Vavilapalli
> Priority: Critical
> Fix For: 0.16.0, 0.16.1, 0.17.0

> Attachments: hadoop-2766

>
> For purposes of performance tuning it should be possible to set some
> environment variables that Hadoop honors before launching the Hadoop daemons.
> For e.g. to set the heap size of the JVM, we should set the HADOOP_HEAPSIZE
> variable. These can be configured through hodrc using the
> gridservice-mapred.envs environment variable. This works for everything
> *except* HADOOP_OPTS, which is also useful, for e.g. to pass in Garbage
> collection parameters to the JVM, like -XX:+UseParallelGC. This is because
> HOD tries to set HADOOP_OPTS from the gridservice-mapred.java-opts variable,
> but it does not read the java-opts variable anywhere properly.
