> Key: HIVE-18776
> URL: https://issues.apache.org/jira/browse/HIVE-18776
> Project: Hive
> Issue Type: Bug
> Components: Materialized views, Metastore
> Affects Versions: 3.0.0
> Reporter: Alan Gates
> Assignee: Jesus Camacho Rodriguez
> Priority: Major
> Attachments: HIVE-18776.01.patch, HIVE-18776.02.patch,
> HIVE-18776.patch

>
> I am seeing occasional failures running metastore tests where operations are
> failing saying that there is no open transaction. I have traced this to a
> race condition in loading the materialized view invalidation cache. When it
> is initialized (either in HiveMetaStoreClient in embedded mode or in
> HiveMetaStore in remote mode) it grabs a copy of the current RawStore
> instance and then loads the cache in a separate thread. But ObjectStore
> keeps state regarding JDO transactions with the underlying RDBMS. So with
> the loader thread and the initial thread both doing operations against the
> RawStore they sometimes mess up each others transaction stack. In a quick
> test I used HMSHandler.newRawStoreForConf() to fix this, which seemed to work.
> A reference to the TxnHandler is also called. I suspect this will run into a
> similar issue.
