Lars Hofhansl commented on HBASE-5617: -------------------------------------- In 0.94+ there are more places where we rollback the memstore. Check out HRegion.mutateRowsWithLocks in 0.94 and HRegion.processRowsWithLocks in 0.96. > Provide coprocessor hooks in put flow while rollbackMemstore. > ------------------------------------------------------------- > > Key: HBASE-5617 > URL: https://issues.apache.org/jira/browse/HBASE-5617 > Project: HBase > Issue Type: Improvement > Components: coprocessors > Reporter: ramkrishna.s.vasudevan > Assignee: ramkrishna.s.vasudevan > Fix For: 0.96.0 > > Attachments: HBASE-5617_1.patch, HBASE-5617_2.patch > > > With coprocessors hooks while put happens we have the provision to create new > puts to other tables or regions.
