I am trying to find out relation of ambari with various log management frameworks.
Hi
What do you mean by "support"? Are you looking after how to monitor Ambari? Or how to splunk a Hadoop Cluster through Ambari?
Ambari is an Management Tool for hadoop. You could compare it with an element manger: it allows you to install, configure and monitor Hadoop Cluster.
The monitoring portion is quite open, it allows you to send the metrics data into a file system (where you could pick up the data via forwarder) or you use the REST API (and the Splunk Addon Builder) to pull the data into Splunk. The logs can be integrated with a forwarder:

There are more options... but what is it what you want to achieve? Of course you could just splunk everything.
