I am trying spark-shell on a single host and got some strange behavior of
spark-shell.
If I run bin/spark-shell without connecting a master, it can access a hdfs
file on a remote cluster with kerberos authentication.
scala> val textFile =
sc.textFile("hdfs://*.*.*.*:8020/user/lih/drill_test/test.csv")
scala> textFile.count()
res0: Long = 9
However, if I start the master and slave on the same host and using
bin/spark-shell --master spark://*.*.*.*:7077
run the same commands
scala> textFile.count()

I figure that when connecting to a master, the job must have been executed
by a child process and the env variables or classpath might be different
from running without master.
Please suggest how to do more troubleshooting and fix this. I am pulling all
hair out...
Thanks so much.
