[jira] [Created] (CASSANDRA-5536) ColumnFamilyInputFormat demands OrderPreservingPartitioner when specifying InputRange with tokens

Lanny Ripple created CASSANDRA-5536:
---------------------------------------

             Summary: ColumnFamilyInputFormat demands OrderPreservingPartitioner when specifying InputRange with tokens
                 Key: CASSANDRA-5536
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-5536
             Project: Cassandra
          Issue Type: Bug
          Components: Hadoop
    Affects Versions: 1.2.3
            Reporter: Lanny Ripple


When ColumnFamilyInputFormat starts getting splits (via getSplits(...) [ColumnFamilyInputFormat.java:101]) it checks to see if a `jobKeyRange` has been set.  If it has been set it attempts to set the `jobRange`.  However the if block (ColumnFamilyInputFormat.java:124) looks to see if the `jobKeyRange` has tokens but asserts that the OrderPreservingPartitioner must be in use.

This if block should be looking for keys (not tokens).  Code further down (ColumnFamilyInputFormat.java:147) already manages the range if tokens are used but can never be reached.
