Re: Potential conflict with org.iq80.snappy in Spark 1.6.0 environment?

2016-03-27 Thread Vasu Parameswaran 
It turned out that there is a conflict for this within the Spark
environment.  This error got resolved after I shaded out org.iq80.snappy
via the maven shade plugin.  Just posting so others may benefit.

Looks like a jar conflict, could you paste the piece of code? and how your
dependency file looks like?

Thanks
Best Regards

Potential conflict with org.iq80.snappy in Spark 1.6.0 environment?

2016-03-18 Thread vasu20 
Hi,

I have some code that parses a snappy thrift file for objects.  This code
works fine when run standalone (outside of the Spark environment).  However,
when running from within Spark, I get an IllegalAccessError exception from
the org.iq80.snappy package.  Has anyone else seen this error and/or do you
have any suggestions?  Any pointers appreciated.  Thanks!

Vasu
