Jean-Marc Spaggiari updated HBASE-8803: --------------------------------------- Attachment: HBASE-8803-v5-0.94.patch Here we go!!! Patch for 0.94 attached with, as asked, a Ruby thread pool. Still working like the previous one. Tested on a 7 nodes cluster. Regular script takes 17 minutes. This one with 12 threads took 6 minutes. Almost a third! I used (RS - 1) * 2 threads. This might be a pretty good sizing rule. Feel free to comment. If it's fine I will apply to trunk and provide the related patch too. Sorry for the delay to get it done. > region_mover.rb should move multiple regions at a time > ------------------------------------------------------ > > Key: HBASE-8803 > URL: https://issues.apache.org/jira/browse/HBASE-8803 > Project: HBase > Issue Type: Bug > Components: Usability > Affects Versions: 0.98.0, 0.94.8, 0.95.1 > Reporter: Jean-Marc Spaggiari > Assignee: Jean-Marc Spaggiari > Fix For: 0.99.0 > > Attachments: 8803v5.txt, HBASE-8803-v0-trunk.patch, > HBASE-8803-v1-0.94.patch, HBASE-8803-v1-trunk.patch, > HBASE-8803-v2-0.94.patch, HBASE-8803-v2-0.94.patch, HBASE-8803-v3-0.94.patch, > HBASE-8803-v4-0.94.patch, HBASE-8803-v4-trunk.patch, HBASE-8803-v5-0.94.patch > > Original Estimate: 48h > Remaining Estimate: 48h > > When there is many regions in a cluster, rolling_restart can take hours > because region_mover is moving the regions one by one. -- This message was sent by Atlassian JIRA (v6.1.4#6159)
