Subject [jira] Commented: (HADOOP-2838) Add HADOOP_LIBRARY_PATH config setting so Hadoop will include external directories for jni
Date Tue, 02 Jun 2009 11:05:07 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-2838?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12715477#action_12715477
] 

Sharad Agarwal commented on HADOOP-2838:
----------------------------------------

Adding a new MiniDFSCluster based test for this looks to be an overkill. Instead can we write
a test by separating this functionality in a method and just testing that? Alternatively we
can add to one of the existing MiniDFSCluster test.

> Currently there is no way to configure Hadoop to use external JNI directories. I propose
we add a new variable like HADOOP_CLASS_PATH that is added to the JAVA_LIBRARY_PATH before
the process is run.
