I want to add that there a regression when using pyspark to read data
from HDFS. its performance during map tasks has gone down approx 1 ->
0.5x. I have tested the 1.0.2 and the performance was fine, but the 1.1
release candidate has this issue. I tested by setting the following
properties to make sure it was not due to these.
set("spark.io.compression.codec","lzf").set("spark.shuffle.spill","false")
in conf object. Let me know if you need further information.
Regards,
Gurvinder
