HDFS Rest Service not available
Hello All,
A bit scared I did something stupid...I killed a few PIDs that were
listening to ports 2183 (kafka), 4042 (spark app), some of the PIDs
didn't even seem to be stopped as they still are running when i do
lsof -i:[port number]
I'm not sure if the problem started after or before I did these kill
commands, but I now can't connect to HDFS or start spark. I can't seem
to access Hue. I am afraid I accidentally killed an important process
related to HDFS. But, I am not sure what it would be as I couldn't
even kill the PIDs.
Is it a coincidence that HDFS failed randomly? Likely that I killed an
important PID? How can I maybe restart HDFS?
Thanks a lot!
Error on Hue:

Ahh, this did the trick, I had to get the name node out of same mode
however before it fully worked.
Thanks!

Re: HDFS Rest Service not available
Posted by Akhil Das <ak...@sigmoidanalytics.com>.
It says your namenode is down (connection refused on 8020), you can restart
your HDFS by going into hadoop directory and typing sbin/stop-dfs.sh and
then sbin/start-dfs.sh
Thanks
Best Regards
