Description

When running a bulk load on a secure environment and loading data into the first region of a table, the request to load the HFile set is dispatched to all Regions for the table. This is reproduced consistently by running IntegrationTestBulkLoad on a secure cluster. The load fails with an exception that looks like:

2013-08-30 07:37:22,993 INFO  [main] mapreduce.LoadIncrementalHFiles: Split occured while grouping HFiles, retry attempt 1 with 3 files remaining to group or split
2013-08-30 07:37:22,999 ERROR [main] mapreduce.LoadIncrementalHFiles: IOException during splitting
