Mubarak Seyed commented on HBASE-4720: -------------------------------------- This JIRA request was opened by my colleague as we need this feature in 0.90 branch as we have a requirement to use atomic update operations in production cluster. If this fix goes only in 0.92 and TRUNK then we need to wait a while. Can't we apply this patch under 0.90.6 branch? I can create a separate patch for 0.92 and TRUNK. Please confirm. Thanks. > Implement atomic update operations (checkAndPut, checkAndDelete) for REST > client/server > ---------------------------------------------------------------------------------------- > > Key: HBASE-4720 > URL: https://issues.apache.org/jira/browse/HBASE-4720 > Project: HBase > Issue Type: Improvement > Reporter: Daniel Lord > Assignee: Mubarak Seyed > Fix For: 0.94.0 > > Attachments: HBASE-4720.v1.patch, HBASE-4720.v3.patch > > > I have several large application/HBase clusters where an application node > will occasionally need to talk to HBase from a different cluster. In order > to help ensure some of my consistency guarantees I have a sentinel table that > is updated atomically as users interact with the system. This works quite > well for the "regular" hbase client but the REST client does not implement > the checkAndPut and checkAndDelete operations. This exposes the application > to some race conditions that have to be worked around. It would be ideal if > the same checkAndPut/checkAndDelete operations could be supported by the REST > client. -- This message is automatically generated by JIRA.
