Eshcar Hillel commented on HBASE-19095: --------------------------------------- [~Apache9] can you please explain again why do we need the {{preMemStoreCompaction(store)}} and the {{postMemStoreCompaction(store)}} before and after {{doCompaction()}} ? What kind of manipulation do we want to allow the user? Is it some preparation work before the compaction that cannot be done in {{preMemStoreCompactionCompactScannerOpen(store)}}?, Is it something equivalent to what is done on store file compaction? > Add CP hooks in RegionObserver for in memory compaction > ------------------------------------------------------- > > Key: HBASE-19095 > URL: https://issues.apache.org/jira/browse/HBASE-19095 > Project: HBase > Issue Type: Sub-task > Components: Coprocessors > Reporter: Duo Zhang > Assignee: Duo Zhang > Fix For: 2.0.0-beta-1 > > Attachments: HBASE-19095.patch > > > This is a hole in our CP hooks. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
