Hitesh Shah commented on MAPREDUCE-3709: ---------------------------------------- @Eli, I don't have a rhel6 host to try and reproduce this and a rhel5 host does not show this issue. Yarn already has fixes in place for malloc arena when running a proper cluster ( yarn-config.sh sets it if not set and yarn sets malloc_arena_max ( if present in the node manager's env ) into the application's env unless its overridden by the user's config. [ Refer to ContainerLaunch#sanitiveEnv, YarnConfiguration.NM_ADMIN_USER_ENV and YarnConfiguration.DEFAULT_NM_ADMIN_USER_ENV). One option to try and fix the test in your case would be change the pom file to have this: {quote} @@ -104,6 +104,7 @@ <configuration> <environmentVariables> <JAVA_HOME>${java.home}</JAVA_HOME> + <MALLOC_ARENA_MAX>4</MALLOC_ARENA_MAX> </environmentVariables> </configuration> </plugin> {quote} Could you try the above change and see if it resolves the test failure in your env? The above change will result in launch_container.sh setting the malloc arena max value to 4. > TestDistributedShell is failing > ------------------------------- > > Key: MAPREDUCE-3709 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-3709 > Project: Hadoop Map/Reduce > Issue Type: Bug > Components: mrv2, test > Affects Versions: 0.23.1 > Reporter: Eli Collins > Priority: Blocker > > TestDistributedShell#testDSShell is failing the assert on line 90 on > branch-23. -- This message is automatically generated by JIRA.
