---------------------------------------

+1. Thanks, Kihwal. Since 2.4.0 is already in RC, I will commit this to trunk 
and branch-2.

> HDFS-5637 fixed the issue for 2.0, but after the new domain socket based 
> local reader, the fix won't work for the old "legacy" short-circuit local 
> reader. This is because DFSInputStream#getBlockReader() catches IOException 
> and disables it when calling BlockReaderFactory.getLegacyBlockReaderLocal().
