>             Project: Apache Apex Malhar
>          Issue Type: Bug
>            Reporter: Yogi Devendra
>            Priority: Minor
>
> 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.
