As part of our daily workflow, we're running a few hundred hive queries that are coordinated through oozie. Recently we're encountering issues where on average a job or two fails - and never the same query. The observed error is:
FAILED: Error in metadata: java.lang.RuntimeException: commitTransaction was called but openTransactionCalls = 0. This probably indicates that there are unbalanced calls to openTransaction/commitTransaction which I've seen was referred to in HIVE-1760 but patched in 0.7. We're running Hive 0.9 (from CDH 4.1 - will redirect to the Cloudera lists if that is a more appropriate form) - any ideas / suggestions where I should start looking? cheers, -James
