Hi Sangjin, In the new scripts, HADOOP_PREFIX is set very early in execution. This happens inside the hadoop_bootstrap function, which executes before hadoop_exec_hadoopenv, so I expect you can use that.
However, HADOOP-11393 proposes reverting HADOOP_PREFIX and switching things back to HADOOP_HOME, so this might be a moving target right now. I haven't looked at the patch in detail yet. https://issues.apache.org/jira/browse/HADOOP-11393 --Chris Nauroth On 5/28/15, 9:36 AM, "Sangjin Lee" <sj...@apache.org> wrote: >Hi folks, > >I noticed this while setting up a cluster based on the current trunk.
