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. The patch testing procedure gives the following results for the patch: [exec] -1 overall. [exec] [exec] +1 @author. The patch does not contain any @author tags. [exec] [exec] +1 tests included. The patch appears to include 24 new or modified tests. [exec] [exec] -1 javadoc. The javadoc tool appears to have generated 1 warning messages. [exec] [exec] +1 javac. The applied patch does not increase the total number of javac compiler warnings. [exec] [exec] +1 findbugs. The patch does not introduce any new Findbugs warnings. [exec] [exec] +1 release audit. The applied patch does not increase the total number of release audit warnings. [exec] > 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. -- This message is automatically generated by JIRA.
