Subject Ambari-1.5.1 command parameters
Date Wed, 06 Aug 2014 02:48:00 GMT
When AmvariServer builds a command for Agent, it need to add in the command
parameters hostLevelParams / db_name, hostLevelParams /
db_driver_filename,but I look at the Agent side code,only in hooks/before-START directory  use to download
the jdbc jar package, 

there is no other place use these parameters, There are other uses?

In addition, tables job, task and taskAttempt in the Ambari database,   is
to record information of Mapreduce Job? If so, how to configure, make job
information can be saved to the database
