Anoop Sam John commented on HBASE-15027: ---------------------------------------- CompactedHFilesDischarger is started per Region now and this patch seems not removing that code? It starts the chore newly in RS level but not removed the old code. > Refactor the way the CompactedHFileDischarger threads are created > ----------------------------------------------------------------- > > Key: HBASE-15027 > URL: https://issues.apache.org/jira/browse/HBASE-15027 > Project: HBase > Issue Type: Bug > Reporter: ramkrishna.s.vasudevan > Assignee: ramkrishna.s.vasudevan > Fix For: 2.0.0 > > Attachments: HBASE-15027.patch, HBASE-15027_1.patch, > HBASE-15027_2.patch, HBASE-15027_3.patch, HBASE-15027_3.patch, > HBASE-15027_4.patch > > > As per suggestion given over in HBASE-14970, if we need to create a single > thread pool service for the CompactionHFileDischarger we need to create an > exectuor service in the RegionServer level and create discharger handler > threads (Event handlers) and pass the Event to the new Exectuor service that > we create for the compaction hfiles discharger. What should be the default > number of threads here? If a HRS holds 100 of regions - will 10 threads be > enough? This issue will try to resolve this with tests and discussions and > suitable patch will be updated in HBASE-14970 for branch-1 once this is > committed. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
