Andrew Purtell resolved HBASE-6390. ----------------------------------- Resolution: Duplicate Dup of HBASE-3787 > append() and increment() may result in inconsistent result on retries. > ---------------------------------------------------------------------- > > Key: HBASE-6390 > URL: https://issues.apache.org/jira/browse/HBASE-6390 > Project: HBase > Issue Type: Bug > Affects Versions: 0.94.0, 0.96.0 > Reporter: Ashutosh Jindal > > append() and increment() api can give inconsistent result in following > scenarios : > 1- For eg, if the client does not receive the response in the specified time, > it retries. Now the first call to increment/append is already done and this > retry will again make the operation to succeed. > 2- Now if the sync() to WAL fails we get an IOException, on getting an > exception there is a retry done which again results in the doing the > increment/append again. > When may need some sort of roll back for the second problem. > For the first one we need to see how to handle this. -- This message is automatically generated by JIRA.
