[jira] [Commented] (SPARK-1719) spark.executor.extraLibraryPath isn't applied on yarn

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

    [ https://issues.apache.org/jira/browse/SPARK-1719?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14129644#comment-14129644 ] 

Wilfred Spiegelenburg commented on SPARK-1719:
----------------------------------------------

I looked through the pull request linked here and the pull request that closed the linked one and I can not see any reference to the spark.executor.extraLibraryPath. I went through the trunk and the only place I can see it is in the mesos code.
Can you explain how the change in https://github.com/apache/spark/pull/1031 fixes the issue reported without referencing the setting at all?

> Looking through the code for spark on yarn I don't see that spark.executor.extraLibraryPath is being properly applied when it launches executors.  It is using the spark.driver.libraryPath in the ClientBase.
> Note I didn't actually test it so its possible I missed something.
> I also think better to use LD_LIBRARY_PATH rather then -Djava.library.path.  once  java.library.path is set, it doesn't search LD_LIBRARY_PATH.  In Hadoop we switched to use LD_LIBRARY_PATH instead of java.library.path.  See https://issues.apache.org/jira/browse/MAPREDUCE-4072.  I'll split this into separate jira.
