Mike Drob updated HBASE-5617: ----------------------------- Fix Version/s: (was: 2.0.0) 2.0.0-alpha-4 > 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: 2.0.0-alpha-4 > > 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. These puts can be done with writeToWal as > false. > In 0.94 and above the puts are first written to memstore and then to WAL. If > any failure in the WAL append or sync the memstore is rollbacked. > Now the problem is that if the put that happens in the main flow fails there > is no way to rollback the > puts that happened in the prePut. > We can add coprocessor hooks to like pre/postRoolBackMemStore. Is any one > hook enough here? -- This message was sent by Atlassian JIRA (v6.4.14#64029)
