The hbase-spark integration tests run (and fail) for me locally whenever I build master with 'mvn clean install -DskipITs' .
HBaseConnectionCacheSuite: - all test cases *** FAILED *** 2 did not equal 1 (HBaseConnectionCacheSuite.scala:92) Saw it but had to ignore/triage to get something else done. We have a weird situation where integration tests run when they shouldn't locally yet no tests run at all for patch process? I would like to see Spark behave like the other modules. I remember filing a JIRA asking that hbase-spark honor -DskipITs. It still doesn't. Meanwhile, it does its own thing with '-DskipSparkTests', which is not appropriate given that none of the other modules have their own distinct control parameters. There also doesn't seem to be a distinction between unit tests and integration tests. The 'test' target does nothing. Everything happens during the 'integration-test' phase. Is this a Spark limitation?
