I did a full removal of all traces of hadoop. When I was re-adding the
hosts, I got a message from host inspector to say no route to host for each
of my data nodes. The services installed anyway, and they started ok. But I
cant do a test job. I get a message that
ERROR hdfs.DFSClient: Failed to close file
/user/hdfs/PiEstimator_TMP_3_141592654/in/part0 could only be replicated to
0 nodes instead of minReplication (=1). There are 3 datanode(s) running
and 3 node(s) are excluded in this operation.
Any idea what may be up here?
IPTables and selinux are off on all hosts.

The document you show is for removing Cloudera Manager entirely (which -
depending on your responses to the removal script - may or may not delete
the entire Cloudera Manager database). You could instead just remove a host
from the cluster in the Hosts tab [https://ccp.cloudera.com/display/ENT45DOC/Deleting+Hosts],
return it to a fresh state by removing any RPM's for CDH and CM bits, then
re-add it as a brand new host through the Add Hosts Wizard.
