Subject [jira] Commented: (PIG-120) support hadoop map reduce in loal mode

Alan Gates commented on PIG-120:
--------------------------------

Based on your comments in https://issues.apache.org/jira/browse/PIG-119, my understanding
is that you want to be able to run the existing pig tests in hadoop's local mode.  But this
patch provides a different test that runs in local mode.  Is this not a step in the wrong
direction?

> 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.
