> The intention of AssignProcedure#COMPARATOR is to put the regions in the following order:
> meta regions
> system table regions
> user table regions
> However, the current implementation may produce incorrect sort order.
> With the modified test, the test fails with:
> {code}
> testComparatorWithMetas(org.apache.hadoop.hbase.master.snapshot.TestAssignProcedure) Time elapsed: 0.038 sec <<< FAILURE!
> junit.framework.AssertionFailedError
> at org.apache.hadoop.hbase.master.snapshot.TestAssignProcedure.testComparatorWithMetas(TestAssignProcedure.java:88)
> {code}
