pyspark change environment and serializer

Change Configuration / Environment

Often it is important to change a core configuration setting in pyspark before running (like a serializer, PYTHONHASHSEED for python3 users, or

from pyspark import SparkContext
from pyspark.serializers import PickleSerializer
new_conf = sc._conf.setExecutorEnv('PYTHONHASHSEED', '1234')
sc.stop()
sc = pyspark.SparkContext(conf = new_conf, serializer = PickleSerializer())

Loading Issue

I think the image loading problem is related to the 'Load group files' checkbox, if you leave it unchecked it seems to work fine.

The error message is:

ERROR Image Reader         3:38       Execute failed: Encountered duplicate row ID  "/Users/mader/Documents/TCGA_DICOMS/DOI/TCGA-17-Z011/1.3.6.1.4.1.14519.5.2.1.7777.9002.119175415668704314181906368452/1.3.6.1.4.1.14519.5.2.1.7777.9002.147921136202653008422021343284/000000.dcm" at row number 3

The test file is attached as 000000.dcm
