[jira] [Commented] (HIVE-9642) Hive metastore client retries don't
happen consistently for all api calls
[ https://issues.apache.org/jira/browse/HIVE-9642?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15025733#comment-15025733 ]

-------------------------------------
+1
Thanks for also adding the test case.
Note for others- this new patch also addresses the cases where MetaStoreClient constructor has errors.

> 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.
