Micah Whitacre commented on CRUNCH-544:
---------------------------------------
Can you provide a test case or sample code for how you are using trying to use
the PTable? I think I know what you are trying to do but seeing code can help
to clarify or understand your use case.
> PTable.materializeToMap returns non-Serializable object
> -------------------------------------------------------

> Key: CRUNCH-544
> URL: https://issues.apache.org/jira/browse/CRUNCH-544
> Project: Crunch
> Issue Type: Improvement
> Components: Core
> Affects Versions: 0.12.0
> 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).
