Jonathan Hsieh commented on HBASE-4326:
---------------------------------------
Hm.. looks like this actually done, but apache jenkins truncates the data so
that it is not available from the build's logs. I've noticed some similar
flaky test failures on my side and will do some runs to try to duplicate
failures and that keeps the full stdout/logs so we can debug.
> Tests that use HBaseTestingUtility.startMiniCluster(n) should shutdown with
> HBaseTestingUtility.shutdownMiniCluster.

> Key: HBASE-4326
> URL: https://issues.apache.org/jira/browse/HBASE-4326
> Project: HBase
> Issue Type: Bug
> Affects Versions: 0.90.4
> Reporter: Jonathan Hsieh
>
> Most tests that use mini clusters use this pattern
> {code}
> private final static HBaseTestingUtility UTIL = new HBaseTestingUtility();
> @BeforeClass
> public static void beforeClass() throws Exception {
> UTIL.startMiniCluster(1);
> }
> @AfterClass
> public static void afterClass() throws IOException {
> UTIL.shutdownMiniCluster();
> }
> {code}
> Some tests (like hbase-4269)
> {code}
> @BeforeClass
> public static void beforeClass() throws Exception {
> UTIL.startMiniCluster(1);
> }
> @AfterClass
> public static void afterClass() throws IOException {
> UTIL.getMiniCluster().shutdown();
> // or UTIL.shutdownMiniHBaseCluster();
> // and likely others.
> }
> {code}
> There is a difference between the two shutdown -- the former deletes files
> created during the tests while the latter does not. This funny state
> persisting (zk or hbase/mr data) may be the cause of strange inter-testcase
> problems when full suites are run.
