Hi,
I am using zeppelin to integrate with DeepSparkContext. I am able to build
zeppelin with independent spark cluster of 1.1.1 version. And gave Spark Master
URL in conf/zeppelin-env.sh. Using the same procedure, I am trying to integrate
zeppelin with deepsparkcontext. Where Startio DeepSparkContext which internally
provides the SparkContext and creates the spark cluster. Now I have given
spark's master url in zeppelin-env.sh. It was ablt to build it. and able to get
the notebook and sc.version also working. I mean if i open a notebook and type
sc.version, I am getting the result as 1.1.1. So scala is working, but if run
any RDD and spark operations like as follows, I am having troubles.
val bankText99 = sc.TextFile("/home/dev004/try/Zeppelin_dev/bank/bank-full.csv")
bankText99.count
Here is my logs..
bankText99: org.apache.spark.rdd.RDD[String] =
/home/dev004/try/Zeppelin_dev/bank/bank-full.csv MappedRDD[3] at textFile at

I dont know what is happening. I tried to change the sparkContext with
deepSparkContext in the code, but getting lot other errors. Please give me some
help on this. I am struck on this from one month.
Looking forward for a quick support.?
