Hi Yin,
Yes there were no new rows. I fixed it by doing a .remember on the context.
Obviously, this is not ideal.

Sorry all for not being clear. I'm using spark 1.4 and the table is a hive

Yeah, it won't technically be supported, and you shouldn't go
modifying the actual installation, but if you just make your own build
of 1.4 for CDH 5.4 and use that build to launch YARN-based apps, I
imagine it will Just Work for most any use case.

It seems this feature was added in Hive 0.13.
https://issues.apache.org/jira/browse/HIVE-4943
I would assume this is supported as Spark is by default compiled using Hive
0.13.1.

Yes, that is correct. You can use this boiler plate to avoid spark-submit.
//The configurations
val sconf = new SparkConf()
.setMaster(spark://spark-ak-master:7077)

Did you try setting the HADOOP_CONF_DIR?

As Sean suggested you can actually build Spark 1.4 for CDH 5.4.x and also
include Hive libraries for 0.13.1, but *this will be completely unsupported
by Cloudera*.
I would suggest to do that only if you just want to experiment with new
features from Spark 1.4. I.e. Run SparkSQL with sort-merge
Which Spark release do you use ?

Based on my experience, YARN containers can get SIGTERM when

- it uses off-heap memory more than what is given by

It's interesting if RDDs are stored internally in a columnar format as well?
Or it is only when an RDD is cached in SQL context, it is converted to

In general, R2 means the line that was fit is a very poor fit -- the
mean would give a smaller squared error. But it can also mean you are
applying R2 where it doesn't apply. Here, you're not performing a
linear regression; why are you using R2?
