Major Description
Current CsvBulkLoadTool doesn't work in a security env due to two reasons:
1) we don't initialize job credentials
2) we don't pass down hbase client config to mapper tasks and it causes a map task not able to talk to either HMaster or Region Severs due to mismatched auth method in Rpc layer with "Authentication is required" error in mapper logs.
From client side, you will see the bulk load map reduce job is hanging there.
