Subject [jira] [Commented] (HIVE-12513) Change LlapTokenIdentifier to use protobuf
Date Tue, 24 Nov 2015 23:52:10 GMT

    [ https://issues.apache.org/jira/browse/HIVE-12513?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15025736#comment-15025736
] 

Siddharth Seth commented on HIVE-12513:
---------------------------------------

Writable just required bytes to be written and read back in. A protobuf instance wrapped in
a writable can be used (used in Hadoop to allow for changes to the token across versions).
Essentially, the serialized bytes end up being interpreted as Protobuf - with support for
unknown fields etc.
