Randy Fox commented on HBASE-14624:
-----------------------------------
The region that took 3 minutes to close was 1.4G compressed.
The evict blocks on close was not working
(https://issues.apache.org/jira/browse/HBASE-14663). The patch for it seems to
solve the problem.
I can give the above change a try.
> BucketCache.freeBlock is too expensive
