[jira] Created: (HIVE-1588) Allowing Hive's metastore when it runs
as a thrift service to run as a pure metadata service and not perform any
filesystem operations
Allowing Hive's metastore when it runs as a thrift service to run as a pure metadata service and not perform any filesystem operations
--------------------------------------------------------------------------------------------------------------------------------------
Key: HIVE-1588
URL: https://issues.apache.org/jira/browse/HIVE-1588
Project: Hadoop Hive
Issue Type: Improvement
Components: Metastore
Reporter: Sushanth Sowmyan
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.

Sushanth Sowmyan commented on HIVE-1588:
----------------------------------------
An additional motivation behind this approach as opposed to simply renewing tokens would be that you also only perform filesystem read operations as the same user that performs write operations(i.e. both on client side)
