Seems like this may be a bug. I looked at
LiveTServerSet.assignTablet() it eventually calls Long.toHexString().
The javadoc for toHexString() says the following.
However, the method we are using to parse the Long can not handle
unsigned longs greater than MAX_LONG. There does not seem to be a
method in long that can parse the output of toHexString(). For
example the following will fail, any negative number will fail.
