Thanks [~gopalv] [~ashutoshc] updated the patch to return -1 for druid record

OK. [~nishantbangarwa] Suggestion is to make getPos() in DruidRecordReader to 
return -1; (instead of 0) so that we never get in this loop.

No, headers are used for other binary sensor formats (footers only work for 
TextInputFormat).

[~ashutoshc]: this patch is probably too fragile - I chased this bug down to 
DruidQueryRecordReader not implementing ::getPos().

This is a good catch, also because it is easier to fix this via the 
block-offset (all handlers can be set to -1, after first entry into loop).

Footer and Header logic is only relevant for csv tables which may contain it. 
For storage handlers we can completely bypass it.

+cc [~ashutoshc] Can you point to more details about the header/footer 
functionality. 
I don't think we need to check any of the checks for header/footer buffer for 
Druid -

Can you please confirm ?

> HiveContextAwareRecordReader add lots of overhead for Druid Scan Queries. 
> See attached flame graph. 
> Looks like the operations for checking for existence of footer/header buffer 
> takes most of time For druid and other storage handlers that do not have 
> footer buffer we should skip the logic for checking the existence for storage 
> handlers atleast.
