Binglin Chang commented on HADOOP-10390:
----------------------------------------
bq. hdfs_read/hdfs_write no longer exists(at least not in hadoop distribution),
but it is used for DFSCIOTest, should they also go into distribution?
I was trying to update the patch to solve all the issues in the jira, but have
not found a proper place to put test_libhdfs_read/test_libhdfs_write,
HADOOP_HOME/bin does not feel like a right place for test programs.
> DFSCIOTest looks for the wrong version of libhdfs
