Subject [jira] [Created] (HIVE-9582) HCatalog should use IMetaStoreClient interface
Date Wed, 04 Feb 2015 20:44:35 GMT
Thiruvel Thirumoolan created HIVE-9582:

             Summary: HCatalog should use IMetaStoreClient interface
                 Key: HIVE-9582
             Project: Hive
          Issue Type: Improvement
          Components: HCatalog, Metastore
    Affects Versions: 0.13.1, 0.14.0
            Reporter: Thiruvel Thirumoolan
            Assignee: Thiruvel Thirumoolan
             Fix For: 0.14.1

Hive uses IMetaStoreClient and it makes using RetryingMetaStoreClient easy. Hence during a
failure, the client retries and possibly succeeds. But HCatalog has long been using HiveMetaStoreClient
directly and hence failures are costly, especially if they are during the commit stage of
a job. Its also not possible to do rolling upgrade of MetaStore Server.
