Description

TestTaskLauncher and TestTaskTrackerLocalization fail in trunk after the commit of MAPREDUCE-1881 with NPE:

java.lang.NullPointerException
        at org.apache.hadoop.mapred.TaskTracker$TaskInProgress.kill(TaskTracker.java:2978)
        at org.apache.hadoop.mapred.TaskTracker$TaskInProgress.jobHasFinished(TaskTracker.java:2941)
        at org.apache.hadoop.mapred.TaskTracker.purgeJob(TaskTracker.java:1919)
        at org.apache.hadoop.mapred.TestTaskTrackerLocalization.verifyUserLogsRemoval(TestTaskTrackerLocalization.java:816)
        at org.apache.hadoop.mapred.TestTaskTrackerLocalization.testJobFilesRemoval(TestTaskTrackerLocalization.java:897)

java.lang.NullPointerException
        at org.apache.hadoop.mapred.TaskTracker$TaskInProgress.kill(TaskTracker.java:2978)
        at org.apache.hadoop.mapred.TaskTracker$TaskInProgress.jobHasFinished(TaskTracker.java:2941)
        at org.apache.hadoop.mapred.TaskTracker.purgeTask(TaskTracker.java:1981)

        at org.apache.hadoop.mapred.TestTaskLauncher.testExternalKillForLaunchTask(TestTaskLauncher.java:95)

NPE happens because taskTracker.myInstrumentation is not initialized.
