Subject [jira] Created: (HIVE-1539) Concurrent metastore threading problem
Date Fri, 13 Aug 2010 15:38:19 GMT
Concurrent metastore threading problem 

                 Key: HIVE-1539
                 URL: https://issues.apache.org/jira/browse/HIVE-1539
             Project: Hadoop Hive
          Issue Type: Bug
          Components: Metastore
    Affects Versions: 0.7.0
            Reporter: Bennie Schut
            Assignee: Bennie Schut

When running hive as a service and running a high number of queries concurrently I end up
with multiple threads running at 100% cpu without any progress.

Looking at these threads I notice this thread(484e):
at org.apache.hadoop.hive.metastore.ObjectStore.getMTable(ObjectStore.java:598)

But on a different thread(63a2):
at org.apache.hadoop.hive.metastore.model.MStorageDescriptor.jdoReplaceField(MStorageDescriptor.java)
