[SPARK-12654] sc.wholeTextFiles with spark.hadoop.cloneConf=true failâ¦
â¦s on secure Hadoop
https://issues.apache.org/jira/browse/SPARK-12654
So the bug here is that WholeTextFileRDD.getPartitions has:
val conf = getConf
in getConf if the cloneConf=true it creates a new Hadoop Configuration.
Then it uses that to create a new newJobContext.
The newJobContext will copy credentials around, but credentials are only
present in a JobConf not in a Hadoop Configuration. So basically when it is
cloning the hadoop configuration its changing it from a JobConf to
Configuration and dropping the credentials that were there. NewHadoopRDD just
uses the conf passed in for the getPartitions (not getConf) which is why it
works.
