[jira] [Commented] (YARN-115) yarn commands shouldn't add "m" to the heapsize

    [ https://issues.apache.org/jira/browse/YARN-115?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13461318#comment-13461318 ] 

Harsh J commented on YARN-115:
------------------------------

Do we even need these specific specifiers? Most users have been content with injecting their own style of -Xmx into the *_OPTS parameters today? Though yeah, that *shouldn't* have been the case.

> the yarn commands add "m" to the heapsize. This is unlike the hdfs side and the the old jt/tt used to do.
>     JAVA_HEAP_MAX="-Xmx""$YARN_RESOURCEMANAGER_HEAPSIZE""m"
>     JAVA_HEAP_MAX="-Xmx""$YARN_NODEMANAGER_HEAPSIZE""m"
> We should not be adding in the "m" and allow the user to specify units.
