Re: passing SparkContext as parameter

can i use this sparkContext on executors ?? In my application, i have scenario of reading from db for certain records in rdd. Hence I need sparkContext to read from DB (cassandra in our case), If sparkContext couldn't be sent to executors , what is the workaround for this ?? On Mon, Sep 21,

Re: passing SparkContext as parameter

sparkConext is available on the driver, not on executors. To read from Cassandra, you can use something like this: https://github.com/datastax/spark-cassandra-connector/blob/master/doc/2_loading.md *Romi Kuntsman*, *Big Data Engineer* http://www.totango.com On Mon, Sep 21, 2015 at 2:27 PM,

You can use broadcast variable for passing connection information. Cheers > On Sep 21, 2015, at 4:27 AM, Priya Ch wrote: > > can i use this sparkContext on executors ?? > In my application, i have scenario of reading from db for certain records in > rdd. Hence I
