Description

TestAccessController is waiting on table to be enabled and after that tries to lookup the region. but if the machine is slow, that region may not be assigned yet.

TEST_UTIL.waitTableEnabled(TEST_TABLE.getTableName());
HRegion region = TEST_UTIL.getHBaseCluster().getRegions(TEST_TABLE.getTableName()).get(0);
