Subject [jira] [Commented] (HIVE-12270) Add DBTokenStore support to HS2 delegation token
Date Thu, 14 Jan 2016 21:49:39 GMT

    [ https://issues.apache.org/jira/browse/HIVE-12270?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15098946#comment-15098946

Robert Kanter commented on HIVE-12270:
--------------------------------------

Oozie needs this to work 100% of the time with secure HS2 HA.  Otherwise, the Oozie server
can get a delegation token from one HS2 server, but the actual query might run against another
HS2 server, which won't recognize the HS2 delegation token.

> DBTokenStore was initially introduced by HIVE-3255 in Hive-0.12 and it is mainly for
HMS delegation token. Later in Hive-0.13, the HS2 delegation token support was introduced
by HIVE-5155 but it used MemoryTokenStore as token store. That the HIVE-9622 uses the shared
RawStore (or HMSHandler) to access the token/keys information in HMS DB directly from HS2
seems not the right approach to support DBTokenStore in HS2. I think we should use HiveMetaStoreClient
in HS2 instead.
