Stefan Groschupf updated PIG-120:
---------------------------------
Attachment: PIG-120_v_1.patch
A patch that allows to run pig in mapreduce mode but uses the hadoop
localjobrunner. This is for sure not the most elegant solution but a starting
point. As mentioned in PIG-121 I guess HExecutionEngine and Co need a cleanup
anyhow.
This patch would be very useful for phase 1 of pig-119. It would be great if we
can get this into trunk as a starting, since I guess PIG-121 will require some
more discussion and work.
> support hadoop map reduce in loal mode

>
> Currently pig support mapreduce and local as execution modes.
> LocalExecutionEngine is used for local and HExecutionEngine for map reduce.
> HExecutionEngine always expect that hadoop runs as cluster with a name node
> and jobtracker listing on a port.
> Though, hadoop can also run in a local mode (LocalJobRunner) this would give
> several advantages.
> First it would speed up the test suite significant. Second it would be
> possible to debug map reduce plans easily.
> For example we was able to debug and reproduce PIG-110 with this method.
