Re: MLLIB and Openblas library in non-default dir
thanks Xiangrui I'll try it. BTW: spark-submit is a standalone program (bin/spark-submit). Therefore, JVM has to be executed after spark-submit script Am I correct?

Re: MLLIB and Openblas library in non-default dir
spark-submit may not share the same JVM with Spark master and executors. On Tue, Jan 6, 2015 at 11:40 AM, Tomas Hudik xhu...@gmail.com wrote: thanks Xiangrui I'll try it.
