Subject [jira] [Updated] (HBASE-12277) Refactor bulkLoad methods in AccessController to its own interface
Date Wed, 15 Oct 2014 23:28:33 GMT

     [ https://issues.apache.org/jira/browse/HBASE-12277?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

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.
