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.
