Volodymyr Vysotskyi created DRILL-6920:
------------------------------------------

             Summary: Fix TestClient.testBasics() yarn test failure
                 Key: DRILL-6920
                 URL: https://issues.apache.org/jira/browse/DRILL-6920
             Project: Apache Drill
          Issue Type: Bug
    Affects Versions: 1.15.0
            Reporter: Volodymyr Vysotskyi
            Assignee: Volodymyr Vysotskyi
             Fix For: 1.15.0


{{TestClient.testBasics()}} test checks error messages for the case of usage non-existent commands. But it contains block for help command which exists in yarn and supported by Drill (see {{CommandLineOptions.Command}} enum).

This test shares the same {{TestContext}} instance for all the tests, but for some envs, {{TestContext.getOut()}} may return the result of the execution of previous block. So for some systems this test passes and for other may fail.

The solution is to add {{TestContext.resetOutput()}} calls for every test block and remove block with {{help}} command since it contradicts test javadoc.
