[jira] [Commented] (MAHOUT-1894) Add support for Spark 2x backend
[ https://issues.apache.org/jira/browse/MAHOUT-1894?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15849309#comment-15849309 ]
Trevor Grant commented on MAHOUT-1894:
--------------------------------------
When building Mahout against spark 2.0.2 I get one warning
```
[WARNING] /home/rawkintrevo/gits/mahout-local/spark/src/test/scala/org/apache/mahout/sparkbindings/drm/DrmLikeSuite.scala:127: warning: constructor SQLContext in class SQLContext is deprecated: Use SparkSession.builder instead
[WARNING] val sqlContext= new org.apache.spark.sql.SQLContext(sc)
```
And then in the tests a lot of whining about
```
Exception encountered when invoking run on a nested suite - requirement failed: MAHOUT_HOME is required to spawn mahout-based spark jobs *** ABORTED ***
java.lang.IllegalArgumentException: requirement failed: MAHOUT_HOME is required to spawn mahout-based spark jobs
```
