Andrew Purtell commented on HBASE-15066:
----------------------------------------
This was marked as in 0.98.17 but I couldn't find it in 0.98 branch history. I
suspect I had it queued up to go on a working branch but never pushed it up.
Have done so now. Fix version is now 0.98.18.

> From an internal request from a user:
> {quote}
> HBase comes with a canary tool which is very useful, but a few minor changes
> would make it substantially better. Specifically, you don't know what it's
> testing until it completes the test, so if it hangs, you can't tell where
> it's hanging. For example, if I run it with the -regionserver option, it
> sends get requests to each of the regionservers in some random order...
> And the same goes for the non-default mode, which hits each region for each
> table.
> If it would just print a message prior to each 'get', it would be extremely
> helpful.
> {quote}
> This patch:
> - Adds debug statements for pre-operation steps.
> - Adds bin/hbase canary support
> - Fixes table names with patterns where the pattern was not matched
> previously.
