[jira] [Created] (CRUNCH-544) PTable.materializeToMap returns non-Serializable object

Mārtiņš Kalvāns created CRUNCH-544:
--------------------------------------

             Summary: PTable.materializeToMap returns non-Serializable object
                 Key: CRUNCH-544
                 URL: https://issues.apache.org/jira/browse/CRUNCH-544
             Project: Crunch
          Issue Type: Improvement
            Reporter: Mārtiņš Kalvāns
            Priority: Minor


In org/apache/crunch/impl/dist/collect/PTableBase.java materializeToMap returns org.apache.crunch.materialize.MaterializableMap object that is not serializable ergo can not be used directly in Crunch api after.

Also it uses poor performant AbstractMap base class that could be issue is someone assumes that this map will be very efficient lookup table (probably most common use case).
