Description

To integrate with Secure Hadoop, filesystem accesses would require an auth token, which has an expiry. Thus, if we were running hive with a thrift metastore server, the server process would need to frequently renew tokens.

One potential way of dealing with that is to have the metastore server be a pure metadata service, and not perform any filesystem operations, which is taking the approach HIVE-1476 takes a step further, extending it for reads as well as writes.
