There are quite a few limitations today to be used in Falcon.
* Api does not return the table type, External or Managed, required for Eviction
* There is no partition filter API in webhcat, again required for evicting candidate partitions. The current API returns all partitions and server could run OOM
* Does not support proxy doAs, which is required for secure falcon since webhcat itself acts as a proxy for Hive
* webhcat does not use Hive/HCatalog API but uses bin scripts which needs Hive, Hadoop and HCatalog t o be installed and env exported. This is a major limitation for Falcon integration tests which brings up these services when int-tests run
I plan to add jira's in Hive for these.

> HCat integration is currently done through thrift interface (FALCON-96). Though the WebHCat implementation is coded up, it is yet to be tested or integrated. It would be good to have that done.
