> Improve the retry strategy for Metastore client and server
> ----------------------------------------------------------
>
> Key: HIVE-27097
> URL: https://issues.apache.org/jira/browse/HIVE-27097
> Project: Hive
> Issue Type: Improvement
> Components: Hive
> Affects Versions: 4.0.0-alpha-2
> Reporter: Wechar
> Assignee: Wechar
> Priority: Major
> Labels: pull-request-available
> Time Spent: 2h 10m
> Remaining Estimate: 0h

> *Background*
> Hive provides *{{RetryingMetaStoreClient}}* and *{{RetryingHMSHandler}}* to
> do retry when thrift request failed:
> * RetryingMetaStoreClient will retry for *thrift related exception* and some
> *MetaException*
> * RetryingHMSHandler will retry for all {*}JDOException{*} or
> *NucleusException*.
> *Motivation*
> Current retry mechanism will lead to many unnecessary retries in both client
> and server. To simplify the process, we introduce following retry mechanism:
> * Client side only concerns the error of communication, i.e.,
> {*}TTransportException{*}.
> * Server side can skip some exceptions which always turn to fail even with
> retry, like {*}SQLIntegrityConstraintViolationException{*}.
