Sergey Shelukhin commented on HBASE-3787: ----------------------------------------- Yeah, we could also just do this. This won't solve the JIRA as stated though... Maybe we can do that for 0.95 and keep this jira as major for future effort. > Increment is non-idempotent but client retries RPC > -------------------------------------------------- > > Key: HBASE-3787 > URL: https://issues.apache.org/jira/browse/HBASE-3787 > Project: HBase > Issue Type: Bug > Components: Client > Affects Versions: 0.94.4, 0.95.2 > Reporter: dhruba borthakur > Assignee: Sergey Shelukhin > Priority: Critical > Fix For: 0.95.1 > > Attachments: HBASE-3787-partial.patch > > > The HTable.increment() operation is non-idempotent. The client retries the > increment RPC a few times (as specified by configuration) before throwing an > error to the application. This makes it possible that the same increment call > be applied twice at the server. > For increment operations, is it better to use > HConnectionManager.getRegionServerWithoutRetries()? Another option would be > to enhance the IPC module to make the RPC server correctly identify if the > RPC is a retry attempt and handle accordingly. -- This message is automatically generated by JIRA.
