FAQ
Hi Geoffrey,

I would make sure that you have installed the cloudera-manager-daemons
package on all hosts. Sounds like it's missing.

The full CM upgrade guide is here:

Thanks,
Darren

5 of the 7 nodes (4 data nodes and 1 master) fail to run the Host
Inspector correctly:
Error seems to be: Error: Could not find or load main class
com.cloudera.cmf.inspector.Inspector
which sounds like either something's not installed or there's a classpath
problem.

Anyway, I'm leaving for the night, but what should the next thing I look
at be?

Thanks for all your help!

Geoffrey

Actually, it'll say "Not installed or path incorrect" (and not "Missing").

If you run Host Inspector and check results, does any CDH component show
up as "Missing"?

One agent is complaining that there's < 20% space (it's just a
Zookeeper/JournalNode), but most are fine. All hosts but that node are
green, though the cluster's in a weird state because the CDH 4.3 RPMs are
uninstalled, but the CDH 5.0 parcel's downloaded/distributed but not
installed.

Can you check if all your agents are reporting good health?
