>
> 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.
