[jira] [Commented] (HADOOP-13773) wrong HADOOP_CLIENT_OPTS in
hadoop-env on branch-2
[ https://issues.apache.org/jira/browse/HADOOP-13773?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15622349#comment-15622349 ]
Fei Hui commented on HADOOP-13773:
----------------------------------
in conf/hadoop-env.sh,
export HADOOP_CLIENT_OPTS="-Xmx512m $HADOOP_CLIENT_OPTS"
when i set HADOOP_HEAPSIZE ,and run 'hadoop jar ...', jvm args is not work.
i see, in bin/hadoop,
exec "$JAVA" $JAVA_HEAP_MAX $HADOOP_OPTS $CLASS "$@"
HADOOP_OPTS is behind JAVA_HEAP_MAX, so HADOOP_HEAPSIZE is not work.
for example i run 'HADOOP_HEAPSIZE=1024 hadoop jar ...' , the java process is 'java -Xmx1024m ... -Xmx512m...', then Xmx512m is valid， and Xmx1024m is invalid
