Madhan Neethiraj updated HBASE-12277:
-------------------------------------
Description:
SecureBulkLoadEndPoint references couple of methods, prePrepareBulkLoad() and
preCleanupBulkLoad(), implemented in AccessController i.e. direct coupling
between AccessController and SecureBuikLoadEndPoint classes.
SecureBulkLoadEndPoint assumes presence of AccessController in secure-cluster.
If HBase is configured with another coprocessor for access-control,
SecureBulkLoadEndPoint fails with NPE.
To remove this direct coupling, bulk-load related methods in AccessController
should be refactored to an interface; and have AccessController implement this
interfaces. SecureBulkLoadEndPoint should then look for coprocessors that
implement this interface, instead of directly looking for AccessController.
> Refactor bulkLoad methods in AccessController to its own interface
