> When there is single large file in the input directory, and we have multiple partitions
for BlockReader and sequencialFileRead is set to true.
> Only one BlockReader instance should be active; other BlockReader instances should remain
idle.
> This is because sequencialFileRead makes sure that blocks of the file are read serially
by same BlockReader instance. 
> Observed behavior is all BlockReader instances are reading data which means sequencialFileRead
property is not functioning as expected.
