Andrew Wong commented on KUDU-2153:
-----------------------------------
I'm more inclined to go down the latter route. As striping metadata/WALs seems
to be looming over the horizon, it's looking like these "special" directories
shouldn't be treated all that specially.
> Servers delete tmp files before obtaining directory lock

> Key: KUDU-2153
> URL: https://issues.apache.org/jira/browse/KUDU-2153
> Project: Kudu
> Issue Type: Bug
> Components: fs
> Affects Versions: 1.2.0, 1.3.1, 1.4.0, 1.5.0
> Reporter: Todd Lipcon
>
> In FsManager::Open() we currently call DeleteTmpFiles very early, before
> starting the block manager. This means that, if you accidentally start a
> tserver while another is running, it's possible for it to delete temporary
> files that are in-use by the running tserver, causing it to exhibit strange
> behavior, crash, etc (as in KUDU-2152).
