Subject [jira] [Commented] (HDFS-6579) TestSocketIOWithTimeout#testSocketIOWithTimeout fails on Power PC

Jinghui Wang commented on HDFS-6579:
------------------------------------

Thanks for the prompt review. Yes, this is for PPC64 Linux.

 I have modified the patch per you suggestion. However, rather than introduce a method that
is as extentsive as the getOSType method, I simply added the detection for PPC64 since there
is no need for detecting other architectures yet. Please let me know if a more extensive method
is necessary.

> SocketOutputStream closes its writer if it's partial written. But on PPC, after writing
for some time, buf.capacity still equals buf.remaining. The reason might be what's written
on PPC is buffered,so the buf.remaining will not change till a flush.
