Hi [~sumitmohanty] 
The change looks good to me.

> In order to utilize SSD as a L2 (bucket) cache, we specify a file location to hbase.bucketcache.ioengine
> hbase.bucketcache.ioengine=file:<filepath>
> The directory location specified to the above parameter could be non-existent or non-accessible.
> Since ambari-agent runs with root permissions, the proposed change here is to read the
'hbase.bucketcache.ioengine' parameter from hbase configuration and see if it points to a
file location (by looking at file: prefix). 
> In case ioengine points to a file, ambari-agent should create the underlying directory
and assign appropriate permissions to hbase:hadoop user.
