Joseph commented on HBASE-15935:
--------------------------------
The walker will cause the Generation phase to fail if it finds an anomaly.
Counters are also kept during the Generation phase that count the number of
"bad" nodes. In general, it prints the same debugging information as the
original Walker tool.
> 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)
