------------------------------
Resolution: Invalid
Assignee: Gabriel Reid
Invalid issue, no need to initialize MapFns in PTypes unless they're being used
for io
> MemPipeline doesn't correctly initialize PTypes MapFns
> ------------------------------------------------------
>
> Key: CRUNCH-55
> URL: https://issues.apache.org/jira/browse/CRUNCH-55
> Project: Crunch
> Issue Type: Bug
> Affects Versions: 0.3.0, 0.4.0
> Reporter: Gabriel Reid
> Assignee: Gabriel Reid
> Attachments: WritableIT.java
>
>
> When a MemPipeline is run, the setContext method (and therefore also the
> initialize method) is not called on the MapFns in PTypes. On PTypes MapFns
> that rely on logic in the initialize method, this causes the pipeline to
> crash.
> This can be shown by using PTable#join with Writable values -- a
> NullPointerException occurs due to the state of the PType input or output
> MapFn not being fully set up.
