Hi Rajesh,

You might be interested in HIVE-4331 for the Pig integration. I think Viraj had tested this
entire use case on a secure cluster.

Subject: HBase --> Hive / HCatalog --> PIG

Hi All,

Has anyone tried out the following usecase in security enabled hadoop cluster?.

1. Create a table in HBase
2. Create a table in Hive pointing to the HBase table created in #1
3. Since HCatalog uses hive metastore, this table will be visible to HCatalog as well.
4. Try to access hive table from PIG via HCatalog

I am able to create a proxy table in Hive pointing to HBase. However, "select * from hbase_test"
throws authentication error.

Any help will be greatly appreciated.
