Subject [Hadoop Wiki] Update of "UnixShellScriptProgrammingGuide" by SomeOtherAccount
Date Mon, 30 Mar 2015 21:16:02 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Hadoop Wiki" for change notification.

The "UnixShellScriptProgrammingGuide" page has been changed by SomeOtherAccount:
https://wiki.apache.org/hadoop/UnixShellScriptProgrammingGuide?action=diff&rev1=18&rev2=19

  
  In addition to all of the variables documented in `*-env.sh` and `hadoop-layout.sh`, there
are a handful of special env vars:
  
- * `JAVA_HEAP_MAX` - This is the Xmx parameter to be passed to Java. (e.g., `"-Xmx1g"`).
 This is present for backward compatibility, however it should be added to `HADOOP_OPTS` via
`hadoop_add_param HADOOP_OPTS Xmx "${JAVA_HEAP_MAX}"` prior to calling `hadoop_finalize`.
+ * `HADOOP_HEAP_MAX` - This is the Xmx parameter to be passed to Java. (e.g., `"-Xmx1g"`).
 This is present for backward compatibility, however it should be added to `HADOOP_OPTS` via
`hadoop_add_param HADOOP_OPTS Xmx "${JAVA_HEAP_MAX}"` prior to calling `hadoop_finalize`.
  
  * `HADOOP_DAEMON_MODE` - This will be set to `start` or `stop` based upon what `hadoop-config.sh`
has determined from the command line options.
