Review comment:
The mainly change is in yarn and k8s, not in spark, we should adapt to it.
What I claim here is that, with this code, the environment configuration in
JVM and python worker won't be same, and the configure passed into python
worker is awful.
You can try `--conf
spark.executorEnv.LD_LIBRARY_PATH=$PYTHONHOME/lib/python2.7/site-packages:$
LD_LIBRARY_PATH`, and find what I mean.
