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.
