Fix token usage from HCat
-------------------------
Key: HCATALOG-69
URL: https://issues.apache.org/jira/browse/HCATALOG-69
Project: HCatalog
Issue Type: Improvement
Reporter: Sushanth Sowmyan
We need to fix the following issues in HCat
+ Token cancellation semantics of the Hive token needs storing the signature
- rework to remove this
+ Likewise, there's no good need for the token signature and tokenstrform of
the JobTracker token, and that might actually be a security problem there. That
needs to be reworked to just scan tokens in current scope, and if found, and we
have a flag set to indicate that it was a token we fetched, then we cancel
as-is. Current code mimics hive-token behaviour and needs to be changed.
