Ivan A. Veselovsky updated PIG-2898:
------------------------------------
Attachment: PIG-2898-trunk-5.patch
Hi, Rohini,
all the mentioned suggestions were adderessed in the patch #5. This patch is
cumulative: it aggregates all the changes made in previous patches.
Notes:
* In parallellized mode context (like "[myfile.conf-MyGroup]" is printed
*after* the results due to formatting issues (some contexts are too long).
* In trunk branch test streaming_local.conf/StreamingLocal_11 hangs in local
mode (observed in both sequential and parallel execution modes). So, I
recommend to comment it out to get full results.
* The local dir parametrized with 'hadoop.mapred.local.dir' in ant, or
'HADOOP_MAPRED_LOCAL_DIR' in environment.
* Debug output parametrized with 'e2e.debug' in ant, or 'E2E_DEBUG' in
environment.

> Project: Pig
> Issue Type: Improvement
> Components: e2e harness
> Affects Versions: 0.10.0
> Reporter: Andrey Klochkov
> Assignee: Ivan A. Veselovsky
> Labels: test
> Attachments: PIG-2898-against-trunk-2.patch,

> 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.
