> Affects Versions: 1.0.3
> Reporter: Karthik Kambatla

> The source for occasional failure of TestLostTracker seems like the following:
> On job completion, JobHistoryFilesManager#run() spawns another thread to move
> history files to done folder. TestLostTracker waits for job completion,
> before checking the file format of the history file. However, the history
> files move might be in the process or might not have started in the first
> place.
> The attachment (force-TestLostTracker-failure.patch) helps reproducing the
> error locally, by increasing the chance of hitting this race.
