Connect to two different HDFS servers with different usernames

[Wayne Song <wa...@gmail.com>]

Is there any way to get data from HDFS (e.g. with sc.textFile) with two
separate usernames in the same Spark job?  For instance, if I have a file on
hdfs-server-1.com and the alice user has permission to view it, and I have a
file on hdfs-server-2.com and the bob user has permission to view it, I'd
like to be able to do something like:



Is there any way to do something like this?  Or can Spark only connect to
HDFS with the same username that it's running as?
