             Summary: Hive metastore client retries don't happen consistently for all api calls
                 Key: HIVE-9642
                 URL: https://issues.apache.org/jira/browse/HIVE-9642
             Project: Hive
          Issue Type: Bug
    Affects Versions: 1.0.0
            Reporter: Xiaobing Zhou
            Assignee: Xiaobing Zhou


When org.apache.thrift.transport.TTransportException is thrown for issues like socket timeout, the retry via RetryingMetaStoreClient happens only in certain cases.
Retry happens for the getDatabase call in but not for getAllDatabases().
The reason is RetryingMetaStoreClient checks for TTransportException being the cause for InvocationTargetException. But in case of some calls such as getAllDatabases in HiveMetastoreClient, all exceptions get wrapped in a MetaException. We should remove this unnecessary wrapping of exceptions for certain functions in HMC.
