Steve Loughran updated HADOOP-14201:
------------------------------------
    Attachment: HADOOP-14201-001.patch

Patch 001

this adds diagnostics to help find why tests are failing,

* StatsDSink: binding diags of HADOOP-14200
* TestFsShellList: fixes of HADOOP-14199
* TestShellBasedUnixGroupsMapping don't run the tests windows doesn't like
* TestLambdaTestUtils allow for slower machines by not worrying about the retry count, other than a retry must have happened.
* TestWinUtils: more diagnostics of failures

TestWinUtils was still failing;in the "insufficient memory," test; the fix for that appears to be "ask for much more heap". Maybe JRE changes to heap allocation caused the JVM to not ask for that full -Xmx amount, so hide the problem.

My windows test VM is still having problems with hostnames and things; I've given up worrying about that.

> Some of the 2.8.0 tests are failing locally, without much in the way of diagnostics. They may be false alarms related to system, VM setup, performance, or they may be a sign of a problem.
