Steve Loughran created HADOOP-13391:
---------------------------------------
Summary: Make uses of OptionsBuilder synchronized on
OptionsBuilder.class
Key: HADOOP-13391
URL: https://issues.apache.org/jira/browse/HADOOP-13391
Project: Hadoop Common
Issue Type: Improvement
Reporter: Steve Loughran
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
