Binglin Chang commented on HADOOP-10390:
----------------------------------------
Currently I think there are 3 issues we need to fix:
1. libhdfs has a different path and version now, they should be updated
2. 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?
3. DFSCIOTest on exception only prints error message:
System.err.print(e.getLocalizedMessage());
it is so confusing that I took a long time to find the root cause
> DFSCIOTest looks for the wrong version of libhdfs
