Randy Fox commented on HBASE-14624: ----------------------------------- As a baseline (and to install the patch) I did a rolling restart of one RS and it took 7 minutes to move the regions. i waited a few hours for bucket cache to fill up and then moved all the regions off and it took 20 seconds or so and I verified the buckets freed up. > BucketCache.freeBlock is too expensive > -------------------------------------- > > Key: HBASE-14624 > URL: https://issues.apache.org/jira/browse/HBASE-14624 > Project: HBase > Issue Type: Bug > Components: BlockCache > Affects Versions: 1.0.0 > Reporter: Randy Fox > Fix For: 2.0.0, 1.2.0, 1.3.0, 1.0.3, 1.1.3, 0.98.16 > > Attachments: 14624-v1.txt, 14624-v2.txt > > > Moving regions is unacceptably slow when using bucket cache, as it takes too > long to free all the blocks. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
