Andrew Wang updated HDFS-8646:
------------------------------
Attachment: hdfs-8646.002.patch
Thanks for reviewing Colin. I decided to put the cache locations in the outer
for loop since most of the time no replicas are cached, so this saves us an
iteration. Also hit checkstyle, which was complaining about public in an
interface. The other three are line-length warnings.

> Currently we remove blocks from the DD's CachedBlockLists on node failure and
> on cache report, but not on replica invalidation. This can lead to an invalid
> situation where we return a LocatedBlock with cached locations that are not
> backed by an on-disk replica.
