> HADOOP-13179 fixed one place where the non-thread-safe {{OptionsBuilder}}
> class was potentially vulnerable to race conditions. But it didn't address
> all other uses in the codebase, so the problem still exists.
> We need a common object so synchronize off, of which {{OptionsBuilder.class}}
> is the obvious choice
