Jim Brennan commented on HDFS-12453:
------------------------------------
[~eddyxu], [~arp], [~kihwal] we have seen this failure in our internal
branch-2.10 builds.
The original patch applies cleanly, but there were a few issues that I needed
to change for branch-2.10
* Convert the stream() to a StringBuffer for building the list of newDirs
(java7)
* Don't use a lambda for the thread. (java7)
* Change volume.getStorageLocation() to volume.getBasePath().
I've put up a patch for branch-2.10 with these changes. Please let me know if
it would be better to open a new Jira to pull this back to branch-2.10.
