Hi supun,
I think i have fixed couple of previous errors. Now my samoa extension is
working fine with cep. But i am getting a exception with my spark streaming
ml extensions. It was working fine and i did not do any changes to my
previously developed streaming extensions. This error is occured in the
line,
conf = new SparkConf().setMaster("local[*]").setAppName("Linear Regression
Example").set("spark.driver.allowMultipleContexts", "true") ;
sc = new JavaSparkContext(conf);
This what i get and cep server is crashed.
