Jonathan Hsieh commented on HBASE-4326:
---------------------------------------
Actually, if the HBaseTestingUtility calls dump the root dir they are using for
temp hdfs storage to logs/console, we don't need the system properties. It
would be helpful to know where potential leftover files on runs are stored and
to know where if and where temp files are being left behind.
> 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.
