Lars Hofhansl commented on HBASE-3787: -------------------------------------- This is an interesting one. To me the main goal of retries is to ride over a split or region move. If we can isolate that condition and avoid retrying for all "undecided" conditions (the various timeouts) we should be OK. > 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 > Reporter: dhruba borthakur > Assignee: dhruba borthakur > > 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.
