> TestShuffleProvider#testShuffleProviders fails with the following error:
> {noformat}
> at org.junit.Assert.fail(Assert.java:88)
> at org.junit.Assert.assertTrue(Assert.java:41)
> at org.junit.Assert.assertNotNull(Assert.java:621)
> at
> org.apache.hadoop.mapreduce.v2.app.job.impl.TestShuffleProvider.testShuffleProviders(TestShuffleProvider.java:114)
> {noformat}
> The property "commonContainerSpec" is static. As the result, we do not
> recreate common container launch within JVM. This is normal for AM JVM since
> all containers should be run with one context. But this leads to an error
> when we run unit tests in one JVM and expect to recreate container launch
> context.
> We can add a setter for "commonContainerSpec" with "VisibleForTesting"
> annotation and reset CLC in a test if we need it.
> Also, we can cleanup CLC after running tests in @After fixture which create
> CLC but we have too many tests which use TaskAttemptImpl and do not need
> cleanup.
