Hello list,
Today I started Pig on my personal machine after a few weeks to
give 0.11.1 a try. As soon as I issued bin/pig it threw this message on my
terminal :
apache@hadoop:/hadoop/projects/pig-0.11.1$ bin/pig

I was quite surprised at the first look, but then realized that I was
checking out MapR's M3 on my machine a few days ago. Is is normal?I mean
Apache Pig is going to "maprfs" instead of "hdfs" despite the fact that all
my Apache Hadoop daemons were running. Although I removed M3 immediately,
i'm still curious. I would really appreciate if somebody could shed some
light.
Thank you so much for your time.
Warm Regards,
Tariq
