Jerome Boulon commented on CHUKWA-57:
-------------------------------------

BTW, if the queue is full this will block on the queue itself.

>          Issue Type: Bug
>            Reporter: Jerome Boulon
>            Priority: Critical
>
> The FileAdaptor is doing the reading part directly inside the start method and by doing
that it makes the start operation synchronous with the ADD command.
> This will block the remote application.
> The start method should use a queue to add the file to be processed then a background
thread should do the parsing.
> The background thread should be reuse since Thread creation is expensive.
