Vishal Khandelwal commented on HBASE-16399:
-------------------------------------------
Thanks [~apurtell]. For summary intend was that tool should prints all failures
at end of the test. List should not be much or mostly nothing until there are
many failures in the region scan. Currently if 1 region scan fails out of 5K
region then error would be print somewhere in between which needs to searched
and even would scroll up on shell. The intend was to ease the failed region
identification.
I would do other changes.
> Provide an API to get list of failed regions and servername in Canary

> At present HBase Canary tool only prints the failures as part of logs. It
> does not provide an API to get the list or summarizes it so caller can take
> action on the failed host. This Jira would additional API so caller can get
> read or write canary failures.
