ATTACHMENT ID: 12848366 - PreCommit-HIVE-Build > RetryingMetaStoreClient is retrying too aggresievley > ---------------------------------------------------- > > Key: HIVE-13014 > URL: https://issues.apache.org/jira/browse/HIVE-13014 > Project: Hive > Issue Type: Bug > Components: Metastore, Transactions > Affects Versions: 1.0.0 > Reporter: Eugene Koifman > Assignee: Eugene Koifman > Priority: Critical > Attachments: HIVE-13014.01.patch, HIVE-13014.02.patch, > HIVE-13014.03.patch, HIVE-13014.04.patch, HIVE-13014.05.patch, > HIVE-13014.06.patch, HIVE-13014.07.patch > > > Not all metastore operations are idempotent. For example, commit_txn() > consists of > 1. request from client to server > 2. server action > 3. ack to client > If network connection is broken after (or during) 2 but before 3 happens, > RetryingMetastoreClient will retry the operation thus causing an attempt to > commit the same txn twice (sometimes in concurrently) > The 2nd attempt is guaranteed to fail and thus return an error to the caller > (which doesn't know the operation is being retried), while the first attempt > has actually succeeded. Thus the caller thinks commit failed and will likely > attempt to redo the transactions - not what we want in most cases. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
