Example of spinning up a Hbase mock style test for integration testing in scala

Question

I am trying to find an example of how to spin up a Hbase server in a mock or integration style, so I can test my code locally in my IDE. I have tried fake-hbase and hbase testing utility and receive errors especially when trying to start the cluster. Please see below the exception I receive when running the following code:

 hbaseTestUtil = new HBaseTestingUtility(conf)
 hbaseTestUtil.startMiniCluster(3)

the error is as follows:

16/03/14 12:29:00 WARN datanode.DataNode: IOException in BlockReceiver.run():

Has anyone got any examples in scala to do this?

I think this is not an HBase issue, but a Windows one. The path is very close to maximum windows path length. It may be failing to create a file. Try reducing the path in some way. — Martin Serrano, Mar 14 '16 at 15:49
That looks to be it Martin... Thanks! Any idea how I can specify a better base directory to be used with Hbasetestingutility? — eboni, Mar 14 '16 at 22:05
