Description

I scanned the Kudu source code for DeleteDir invocation, there are 2 places: https://github.com/apache/kudu/blob/master/src/kudu/fs/fs_manager.cc#L384 and [https://github.com/apache/kudu/blob/master/src/kudu/fs/fs_manager.cc#L485].
Imagine, I start kudu-tserver twice by mistake, finally only one kudu-tserver started, is it possible that its folder may be removed by another kudu-tserver since it failed to start.
