> The {{RetryingMetaStoreClient}} is used to automatically reconnect to the
> Hive metastore, after client timeout, transparently to the user.
> In case of user impersonation (e.g. Oozie super-user {{oozie}} impersonating
> a Hadoop user {{mithun}}, to run a workflow), in case of timeout, we find
> that the reconnect causes the {{UGI.doAs()}} context to be lost. Any further
> metastore operations will be attempted as the login-user ({{oozie}}), as
> opposed to the effective user ({{mithun}}).
> We should have a fix for this shortly.
