Not able to run parallel instances of ant tests
-----------------------------------------------
Key: MAPREDUCE-925
URL: https://issues.apache.org/jira/browse/MAPREDUCE-925
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: test
Affects Versions: 0.20.1
Reporter: Suman Sehgal
Priority: Minor
Not able to execute two or more parallel instances of ant test.
Scenario:
=======
Executed "TestRecoveryManager" in a loop for 100 times and ran some other
tests in parallel. Encountered following error message in TestRecoveryManager
logs:
[junit] 2009-08-27 10:53:48,724 INFO mapred.TaskTracker
(TaskTracker.java:tryToGetOutputSize(1594)) -
org.apache.hadoop.util.DiskChecker$DiskErrorException: Could not find
taskTracker/jobcache/<job-id>/<attempt-id>/output/file.out in any of the
configured local directories
It seems that new ant test removes the existing mapred local directory itself
and recreates it for current test.
