Check for existing env vars

[jahhulbert-ccri]

Maybe warn? maybe continue?

[ellisbjohns]

and definitely add something that warns against having the ccri /opt/devel (devenv) installed

[jahhulbert-ccri]

good point! will do

[vpipkt]

my solution was to unset HADOOP ACCUMULO YARN ZOOKEEPER related env before starting... seemed to help a lot

[jahhulbert-ccri]

i'll try that out

Posting here because I had a related issue and perhaps save someone time. If on .bin/cloud-local.sh init or on subsequent .bin/cloud-local.sh start you receive an error like this:

Error: Could not find or load main classorg.apache.hadoop.hdfs.server.namenode.NameNode

Your problem is CLASSPATH. For me personally it was an altered HADOOP_PREFIX in .ccri-env.rc. If you Google the error you'll find a few stackoverflow hits saying 'Your problem is CLASSPATH', but it may not be clear which HADOOP env is causing the error.
It may help to env | grep hadoop.

There was an initial commit but I think we'd like to log a warning if they point to somewhere other than dev env...still considering
