Starting up Hue. Potential misconfiguration detected. Fix and restart Hue.

[#1]

Hello all,

Just starting up the system and while it is checking the current configuration, I get the following:

"Configuration files located in /etc/hue/conf .empty"

Potential misconfiguration detected. Fix and restart Hue

down                                  The Oozie server is not available

Oozie Editor/Dashboard     The app won't work without running Oozie server

Pig Editor                            The app won't work without running Oozie server

Would appreciate your step by step help.

Thanks in advance.

So this is just warning you that the Oozie server is not working, so some
of the apps in Hue won't work. I don't believe Oozie is needed for any of
the tutorials in Cloudera Live, so you may just be able to ignore this
depending on what you're wanting to do. However you can get to the bottom
of this by logging to Cloudera Manager, clicking on the Oozie service, and
seeing what's going on. The monitoring may already have figured out what's
wrong and might tell you. Otherwise I'd follow the links to see the logs
for the Oozie process and see what Exceptions, etc. you see.

I ignored it.

After typing

hadoop jar hadoop-mapreduce-examples.jar wordcount /user/cloudera/input /user/cloudera/output

I now get the following message:

Not a valid JAR: /home/cloudera/hadoop-mapreduce-examples.jar

How to resolve this?

Thanks

So since you typed 'hadoop-mapreduce-examples.jar' it's looking for that
JAR in the current directory. You'll need to provide the path to it.
Assuming you're in Cloudera Live (or any other cluster in which CDH was
installed with parcels), if you provide the path
'/opt/cloudera/parcels/CDH/lib/hadoop-mapreduce/hadoop-mapreduce-examples.jar'
it should work. If you're in the QuickStart VM or any other
Linux-packages-based installation, it's in /usr/lib/hadoop-mapreduce
instead.
