Mahadev konar commented on AMBARI-1551:
---------------------------------------
Jos,
Here are a couple of pointers on how the monitoring of hadoop processes are
done on the Ambari Agent side.
Take a look at ambari-agent/src/main/python/ambari_agent/LiveStatus.py.
What we can do is make LiveStatus.py pluggable and also as of now the server
send commands to check for status of each component of the host. We can use
that command to just send a list of components to check for on that host and
send it just once in an hour or so. We can then do active live status checks on
the agents itself using a pluggable module which could be a wrapper around
daemon tools.
Does that sound ok?

> We'd like Ambari to support running the Hadoop daemons under a process
> supervsion solution, such as daemontools-encore. This will also likely
> simplify the code by moving some of the current Ambari functionality into the
> process supervision tool.
