Sean Busbey commented on HDFS-8332:
-----------------------------------

+1 for trunk/branc-3 only. A "Known Issue" note on the next set of branch-2 release notes would be a nice-to-have as well.

Also, I'd like to suggest that we change pre-commit to trigger hadoop-hdfs-httpfs tests automatically for all hadoop-hdfs patches. We've seen problems like this in the past. hadoop-hdfs-httpfs gets patched so infrequently that it's easy to miss it when a hadoop-hdfs change introduces a test failure. As a practical matter, we might not be able to add those tests until the current HDFS test runs get optimized.

Leave a note on HADOOP-11929, [~aw] is already specifying that hadoop-hdfs needs to have hadoop-common built with native bits. Not sure if expanding to "under tests always do this other module if this module changes" will be in scope or a new ticket.

> I could see {{listCacheDirectives()}} and {{listCachePools()}} APIs can be called even after the filesystem close. Instead these calls should do {{checkOpen}} and throws:
> {code}
> java.io.IOException: Filesystem closed
> 	at org.apache.hadoop.hdfs.DFSClient.checkOpen(DFSClient.java:464)
> {code}
