    metastore (mysql) connection problems - hive v0.12

    apache.org | 1 year ago
    java.lang.RuntimeException: commitTransaction was called but openTransactionCalls = 0. This probably indicates that there are unbalanced calls to openTransaction/commitTransaction) but i believe this to be just a symptom of something happening further upstream. examining the hive.log file for this useer (under /tmp/<user>/hive.log) i find this hideous traceback with "bonecp" being the focus of attention. There's nothing wrong with the mysql server metastore especially given it works sometimes. to me i think it has something to do with the connection pooling logic but that's only speculation. before i surrender and rollback to a previous version i ask: Has anyone encountered this before? Or are there any nuggets in the traceback worthy of insight? thanks, Stephen. 2013-12-17 16:54:03,142 ERROR bonecp.ConnectionHandle (ConnectionHandle.java:markPossiblyBroken(297)) - Database access problem.
