Joseph commented on HBASE-15935:
--------------------------------

I've done a bit of testing these on a cluster and am pretty confident in this version. Could I get some review on this patch?

> 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)
