clusterHostInfo is built as the topology of all the components when that
information is needed by agent scripts, most commonly on
install/start/restart commands.
See StageUtils.getClusterHostInfo() to see how it gets built.

How does one go about looking at/adding to clusterHostInfo?
Is there an API call to make to look at those values?

Subject: help....config dictionary errors galore
Hi,
Scott Creeley and I have been trying to get all the services running in the
2.1.GlusterFS stack.
Several of the services won't start due to an error like this:
File
"/usr/lib/python2.6/site-packages/resource_management/libraries/script/config_dictionary.py",
line 75, in __getattr__
raise Fail("Configuration parameter '"+self.name+"' was not found in
configurations dictionary!")
Fail: Configuration parameter 'user_group' was not found in configurations
dictionary!
other configuration paramters are slave_hosts
namenode_hosts
etc...
So while some of these are a parameter I would expect for Hadoop (like
user_group), parameters like namenode_hosts is specific to HDFS.
Therefore, is there a way to create a flag in Ambari that says 'noHDFS' that
can be used to create a conditional around these values? Should this
just be a standard global, or should the value be loaded at a different level,
like a system level property?
HBase seems to have a lot of assumptions around HDFS being installed (ie
loading values from the hdfs-site.xml).
Is there a best practice for such processes?
Let us know.
Thanks,
Erin
