Data Collector won't run and Data Aggregator will not connect to host.

/opt/IMdataCollector/apache-karaf-2.3.0/shutdown.log reads:

manager.osgishell.BundleManager 237 | 185 2.3.1.RELEASE-71 | | Unable to connect to the Data Aggregator or at host "data-agg". Shutting down the Data Collector. This may take up to 10 minutes.

DA karaf.log reads:

| UnknownHostException caught in lookupDAItem(): Name or service not known


Notice that the Data Aggregator is looking for the host instead.

Check the hosts file, it probably looks like:

<IP> <shortHostName_for_DA>
Example: data-agg

Instead of:

<IP> <DA_FQDN> <shortHostName_for_DA>


Restart the DA:

service dadaemon restart
