Stefan Groschupf commented on PIG-120:
--------------------------------------
yeah just set the cluster name to local.
This patch is a beginning - i would love to more explizit support that in the
future.
A related proplem for example is that we can not define a jobtracker and
namenode on different host by today.
The configuration patch will solve some basic problems here - please vote it
for better hadoop local mode support in the future. :)
> 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.
