Overriding this interferes with a HA jobtracker setup.

This is interesting; I have not yet tried the HA jobtracker. This does appear to be the "right thing" to do. I'll have to do some testing to see how this stuff works before merging. |

@brndnmtthws Any chance we could get this merged? |
|
I haven't had a chance to try it. Is it sufficiently tested? |
|
I'd probably say no to be honest, we've tested the failover (HA JT) thoroughly here, but i've not tested it with non-ha. Let's leave it until that happens. I'll get to work on #28 too soon, so maybe they can come together. |

I've tested, seems to work. |

Configuring this option causes issues with track tracker connectivity when using the HA JobTracker configuration mode. I assume the reason this option is set is due to the fact hadoop doesn't require you configure this option on the actual JobTracker, only the clients (and task trackers)?
This probably isn't the right fix, however I wanted to open up discussion. Perhaps we could only set the option if it's not currently configured on the config object?
Would appreciate any thoughts, @brndnmtthws?
