> URL: https://issues.apache.org/jira/browse/HBASE-10435
> Project: HBase
> Issue Type: Bug
> Affects Versions: 0.98.0, 0.99.0, 0.96.1.1
> Reporter: Matteo Bertozzi
> Assignee: Matteo Bertozzi
> Priority: Minor
> Fix For: 0.98.0, 0.96.2, 0.99.0

> Attachments: HBASE-10435-v0.patch

>
> When there are no table or the RS doesn't have regions loaded the canary will
> output an ERROR log.
> {code}
> $ hbase org.apache.hadoop.hbase.tool.Canary -regionserver HOSTNAME
> ERROR No RegionServerInfo found, regionServerName: HOSTNAME
> {code}
> but this ERROR shouldn't be considered as "the region server is not up", so
> we probably reduce the log level to "info" or "debug". (The exit code is
> already notifying that the failure cause is related to "initialization" or
> similar)
