@sryza we can export
PYSPARK_ARCHIVES_PATH=local://xx/pyspark.zip;local://xx/py4j.zip in
spark-env.sh and we also can export
PYSPARK_ARCHIVES_PATH=hdfs://xx/pyspaark.zip. then in SparkSubmit we can
automatically add PYSPARK_ARCHIVES_PATH to yarn's dist files. and then
Spark-on-Yarn can put dist files to YARN distributed cache. these work is same
as Spark assembly jar.
@andrewor14 in my test, the pyspark.zip is 378KB, i think it is very small
than the assembly jar.so it can put it to dist files automatically.
