> In development environments, developers often use local_hadoop for unit and
> developer regression testing. Often these test environments are on
> workstations shared between many developers. When running regressions
> overnight, quite frequently the HMaster process will die due to timeouts if
> the workstation is particularly busy. This sometimes causes HBase errors
> during the tests but more often causes hangs. It would be nice to have a tool
> that will monitor HMaster and if it goes away, try to restart it. It has been
> observed that restarting it often resolves the hangs, allowing the regression
> run to continue.
