• Hadoop Flags: Reviewed

Release Note

Use junit facility to impose timeout on test. Use test category to chose which timeout to apply: small tests timeout after 30 seconds, medium tests after 180 seconds, and large tests after ten minutes.

Updated junit version from 4.11 to 4.12. 4.12 has support for feature used here.

Add this at the head of your junit4 class to add a category-based timeout:

{code}
@Rule public final TestRule timeout = CategoryBasedTimeout.builder().withTimeout(this.getClass()).
      withLookingForStuckThread(true).build();
{code}

Description

Apache9 and octo47 have been working hard at trying to get our builds passing again. They are almost there. TRUNK just failed with a zombie TestMasterObserver. Help the lads out by adding timeouts on all tests so less zombie incidence... will help identify the frequent failing issues.
