------------------------------------
Summary: Multithreaded execution of e2e tests
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.
