Jean-Daniel Cryans commented on KUDU-1867:
------------------------------------------
[~evinhas] this is not a bug, this jira is about improving an error message.
You're still going to get an error due to the underlying issue which might be
that the file has the wrong permissions or something like that.
> Improve the "Could not lock .../block_manager_instance" error message
> ---------------------------------------------------------------------
>
> Key: KUDU-1867
> URL: https://issues.apache.org/jira/browse/KUDU-1867
> Project: Kudu
> Issue Type: Bug
> Components: fs
> Affects Versions: 1.2.0
> Reporter: Jean-Daniel Cryans
> Labels: newbie
>
> It's possible for users to encounter a rather cryptic error when trying to
> run Kudu while it's already running or with a different user than what was
> previously used:
> {code}
> Check failed: _s.ok() Bad status: IO error: Failed to load FS layout: Could
> not lock /path/to/data/block_manager_instance: Could not lock
> /path/to/data/block_manager_instance: lock
> /path/to/data/block_manager_instance: Resource temporarily unavailable (error
> 11)
> {code}
> This is the log line that we FATAL with, so unless you already know what it
> means you're left to your own guessing and log digging. Instead, the error
> message could be more prescriptive.
