Ivan A. Veselovsky updated PIG-2898:
------------------------------------
Patch Info: Patch Available
We provided parallelized mode of the e2e tests execution using
Parallel::ForkManager.
Two parameters affect the behavior:
1) file.fork.factor -- max number of subprocesses when running test
configuration files (.conf);
2) fork.factor -- max number of subprocesses when running tests within one
.conf file.
Total max number of subprocesses canot exceed the product of the 2 values.
Value <= 1 mean no paralellizing.
Example: ant -Dfork.factor=3 -Dfile.fork.factor=3 ... test-e2e
The attached patch is to be applied to
http://svn.apache.org/repos/asf/pig/branches/branch-0.9/ branch.

> Key: PIG-2898
> URL: https://issues.apache.org/jira/browse/PIG-2898
> Project: Pig
> Issue Type: Improvement
> Components: e2e harness
> Reporter: Andrey Klochkov
> Assignee: Andrey Klochkov
>
> Today it takes ~19 hours to run the full set of e2e tests in mapred mode. The
> bottleneck here is the client side, and per our observations it can help a
> lot if the e2e harness would be able to run tests in parallel threads.
> We prototyped changes in e2e harness allowing to run tests in a configurable
> number of threads. Preliminary results show more than 6x reduction in
> execution time when using a small 3-nodes M/R cluster with modest
> configuration. Going to share a patch shortly.
