Elliot Miller commented on HBASE-7196:
--------------------------------------
It looks like isMasterRunning was removed from HBaseAdmin by HBASE-14769 (HBase
2.0.0), and then HBaseAdmin itself was deleted more recently, so the above
discussion over HBaseAdmin is no longer relevant.
As for the original issue, an exception is still being thrown by the shell on
3.0.0-SNAPSHOT:
{code:bash}
elliot@host ~/workspaces/hbase % git show --summary --oneline
8cdb2cca44 (origin/master, origin/HEAD) HBASE-24562: Stabilize master startup
with meta replicas enabled (#1903)

elliot@host ~/workspaces/hbase % mvn clean install -DskipTests
...
elliot@host ~/workspaces/hbase % ./bin/hbase shell
...

ERROR: Failed contacting masters after 1 attempts.

Especially with more recent changes to return objects from shell commands
(rather than just printing information), *I think that propagating this
exception to the user is still the way to go*.
> 'hbase shell status' throws exception when HBase is not running

> Project: HBase
> Issue Type: Bug
> Affects Versions: 0.94.1

> Its kind of a nuisance bug. One would assume that 'status' command should
> simply return something along the lines of "HBase is not running"
