Subject [jira] [Commented] (HADOOP-10390) DFSCIOTest looks for the wrong version of libhdfs
Date Tue, 18 Mar 2014 07:15:46 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-10390?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13938904#comment-13938904
] 

Binglin Chang commented on HADOOP-10390:
----------------------------------------

After apply the patch, libhdfs.so.0.0.0, test_libhdfs_read/write are correctly copied to dest
location, but the DFSCIOTest job failed because the task failed due to libhdfs internal error,
maybe it is my environment's problem, have not found the root cause yet, unlikely it is caused
by the issue here.
