stack commented on HBASE-15935:
-------------------------------

Just saw this. It looks excellent. Can the walker fail the job when it finds an 
anomaly? How is the user signalled? Any more debug emitted when problem found 
that would help w/ debug? Nice one Joesph

> Have a separate Walker task running concurrently with Generator

> Keep track of which linked lists have been flushed in an HBase table, so that 
> we can concurrently Walk these lists during the Generation phase. This will 
> allow us to test:
> 1. HBase under concurrent read/writes
> 2. Availability of data immediately after flushes (as opposed to waiting till 
> the Verification phase)
> The review diff can be found at:
