Hi Kamal!
Thanks for your initiative. Please take a look at MiniDFSCluster /
MiniJournalCluster / MiniYarnCluster etc. In your unit tests you can
essentially start a cluster in a single JVM. You can look at
TestQJMWithFaults.java

Hi ,
I'm a beginner to writing unit tests in hadoop.
As per https://wiki.apache.org/hadoop/HowToDevelopUnitTests the Hadoop Unit
tests are all designed to work on a local machine, rather than a full-scale
Hadoop cluster.
However i do see the Hadoop-QA
https://issues.apache.org/jira/secure/ViewProfile.jspa?name=hadoopqa also runs
unit test cases when it validates a patch for any issue like
https://issues.apache.org/jira/browse/YARN-2459?focusedCommentId=14115586&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14115586
So does this mean it runs unit tests only in single node / local setup for
validating any patches ?
I wish to write some unit tests in a HA env thus i need test in a cluster setup
Thanks,Kamal
