[jira] [Commented] (HADOOP-8476) Remove duplicate VM arguments for hadoop deamon

["Vinay (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HADOOP-8476?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13288594#comment-13288594 ] 

Vinay commented on HADOOP-8476:
-------------------------------

following things will remove the duplicate VM args.

1. Make following changes in hadoop-env.sh
{noformat}
export HADOOP_OPTS=""

export HADOOP_NAMENODE_OPTS="-Dhdfs.audit.logger=${HDFS_AUDIT_LOGGER:-INFO,NullAppender}"
export HADOOP_DATANODE_OPTS=""
export HADOOP_SECONDARYNAMENODE_OPTS="-Dhdfs.audit.logger=${HDFS_AUDIT_LOGGER:-INFO,NullAppender}"

export HADOOP_CLIENT_OPTS="-Xmx128m"
{noformat}

Above change is because, from any script hadoop-config.sh will be the first script called, which inturn call hadoop-env.sh. So appending not required.
Anyway remaining args will be added inside hadoop-config.sh. 

Also hadoop-config.sh will be called again by hdfs-config.sh and yarn-config.sh. 
So args will be appending again and again.

2. Remove calling hadoop-env.sh explicitly from hadoop-daemon.sh

I will post patch in some time.

Any comments on this.. ?
