Subject [jira] [Commented] (HADOOP-9599) hadoop-config.cmd doesn't set JAVA_LIBRARY_PATH correctly
Date Sat, 25 May 2013 01:03:20 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-9599?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13666884#comment-13666884
] 

Chuan Liu commented on HADOOP-9599:
-----------------------------------

Judging from the context, I think it should be HADOOP_COMMON_HOME instead of HADOOP_HOME.
Because the purpose of the script is mainly to include JNI library, i.e. native library, in
Java library path, and native library is a hadoop-common project.
I think it is also good to add some comments as well.

> In Windows, hadoop-config.cmd uses the non-existent-variable HADOOP_CORE_HOME when setting
the JAVA_LIBRAR_PATH variable. It should use HADOOP_HOME.
> The net effect is that running e.g. "hdfs namenode" would error out with UnsatisfiedLinkError
because it can't access hadoop.dll.
