Ashutosh Jindal created HBASE-6390: -------------------------------------- Summary: 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.
