Subject [jira] Commented: (HADOOP-2867) Add a task's cwd to it's LD_LIBRARY_PATH
Date Tue, 20 May 2008 17:03:55 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-2867?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12598360#action_12598360
] 

Arun C Murthy commented on HADOOP-2867:
---------------------------------------

bq. On second thought, adding the directories that may have stuff that is not native libs
at all, kind of does not make senese to add them blindly. Since the users can provide symlinks
in the cwd for the cached libraries. This is not necessary. I removed the code which adds
parent directories of all mapred.cache.localFiles

+1

Christian, does this work for you?

> HADOOP-1660 added the task's cwd to it's java.library.path which means only java task's
can take advantage via System.load or System.loadLibrary... we should enhance it to support
Hadoop Pipes applications by adding it to the LD_LIBRARY_PATH so they can use dlopen/dlsym
etc.
