To generate golden answer files, you need to setup your development environment according to this as follows.

1. Download Hive's 0.13.1 release and set HIVE_HOME.

2. Download all 0.13.1a jars from http://mvnrepository.com/artifact/org.spark-project.hive and replace corresponding jars in $HIVE_HOME/lib.
3. Download kryo 2.21.jar to $HIVE_HOME/lib (Note: 2.22 jar does not work).
4. You may not need this step. But, if a Hive query fails and you find that Hive tries to talk to HDFS or you find weird runtime NPEs, set the following in your test suite...

val testTempDir = Utils.createTempDir()
// We have to use kryo to let Hive correctly serialize some plans.
sql("set hive.plan.serialization.format=kryo")
// Explicitly set fs to local fs.
sql(s"set fs.default.name=file://$testTempDir/")
//sql(s"set mapred.working.dir=${testTempDir}")
// Ask Hive to run jobs in-process as a single map and reduce task.
sql("set mapred.job.tracker=local")

README. After running the new test cases for the first time, golden answer files should be found under the sql/hive/src/test/resources/golden folder.
