> We log the scans at the debug level at various places such as inside _BaseQueryPlan_,
_BaseResultIterators_, _Parallelterators_, etc. To help with debugging, we should also print
the table name that the scan will be scanning. An example of a log line for a scan currently,
is:
> {code:java}
> 19/12/16 22:10:38 DEBUG execute.BaseQueryPlan: Scan ready for iteration: {"loadColumnFamiliesOnDemand":true,"startRow":"","stopRow":"","batch":-1,"cacheBlocks":true,"totalColumns":1,"maxResultSize":-1,"families":{"0":["ALL"]},"caching":2147483647,"maxVersions":1,"timeRange":[0,9223372036854775807]}
> {code}
> OR
> {code:java}
