> After Mavenizing streaming and getting its testcases to use the MiniMRCluster wrapper (MAPREDUCE-3169), 4 testcases fail to pass.
> Following is an assessment of those failures. Note that the testcases have been tweaked only to set the streaming JAR and yarn as the  framework.
>  
> (If these issues are unrelated we should create sub-tasks for each one of them).
> *TestStreamingCombiner*, fails because returned counters don't match assertion. However, counters printed in the test output indicate values that would satisfy the assertion. As Tom has indicated it seems MR/YARN are not passing back counter information to the client API.
> *TestStreamingBadRecords*, the job is failing with the following exception
> {code}
> Application application_1321575850006_0001 failed 1 times due to AM Container for 
> appattempt_1321575850006_0001_000001 exited with  exitCode: 127 due to: 
> .Failing this attempt.. Failing the application.
> {code}
> Difficult to troubleshoot because there are not task logs from Mini MR/YARN  run.
> *TestStreamingStatus* fails in validateTaskStatus() in the following assertion
> {code}
> expected:<[before consuming input > sort]> but was:<[SUCCEEDED]>
> {code}
> *TestUlimit* fails with
> {code}
> org.junit.ComparisonFailure: output is wrong expected:<[786432]> but was:<[unlimited]>
