[jira] [Commented] (HDFS-5708) The CacheManager throws a NPE in the DataNode logs when processing cache reports that refer to a block not known to the BlockManager

Andrew Wang commented on HDFS-5708:
-----------------------------------

Thanks Colin, this looks good. The test is a bit racy, in that it definitely tests the cache report processing code, but the bad block ID might get wiped out by the next cache report before it's seen by the CRM or getBlockLocations. However, both look fine. I also ran the failed Jenkins test successfully on my box. 

+1, will commit shortly.
