You need this line to be in a `finally` block after the `fs.create()` call.
Something like:
val fileName = "." + UUID.randomUUID().toString
val path = new Path(logDir, fileName)
val fos = fs.create(path)
val newLastScanTime =
try {
fos.close()
fs.getFileStatus(path).getModificationTime
} finally {
fs.delete(path)
}
