FAQ
Hello Everybody,

After installing Cloudera Manager successfully on a two node cluster I
encountered a period of inactivity whilst I replaced a failed host node.

However now my Cloudera Manager's health has gone from good to bad. Oozie1,
Hue1, and Hive1 show bad health and all the others show unknown health.

The configuration issues for my Cluster all contain the following message:
No host heartbeat; CDH versions cannot be verified.

I have attached the Configuration Issues file and the Server log file.

When I try the hbase or hdfs Web UI, etc I get the error message: Firefox
can't establish a connection to the server at masternode:60010 or
masternode:50070.

Also no Charts are working (but this has been since installation).

I am due to add two new hosts soon.

How do get Cloudera Manager back to good health ?
