Specifying a bad port for TACHYON_MASTER_ADDRESS can cause an OutOfMemoryError

[nicklan]

If I specify my TACHYON_MASTER_ADDRESS with port 19999 instead of 19998 then I get the following after a few seconds:

Exception in thread "main" java.lang.OutOfMemoryError: unable to create new native thread
    at java.lang.Thread.start0(Native Method)
    at java.lang.Thread.start(Thread.java:679)
    at tachyon.master.MasterClient.connect(MasterClient.java:163)
    at tachyon.master.MasterClient.worker_register(MasterClient.java:780)
    at tachyon.worker.WorkerStorage.<init>(WorkerStorage.java:298)
    at tachyon.worker.Worker.<init>(Worker.java:65)
    at tachyon.worker.Worker.createWorker(Worker.java:167)
    at tachyon.worker.Worker.main(Worker.java:218)

My setup is a bit odd, so I'm not sure how reproducible this is, but it seems bad regardless.

Agree. 19999 is the webui port. We need to find a solution to the master service port safe.
