Alexey Kudinkin created HUDI-2831:
-------------------------------------

             Summary: Make sure usages of any `DateFormat`-based components are 
thread-safe
                 Key: HUDI-2831
                 URL: https://issues.apache.org/jira/browse/HUDI-2831
             Project: Apache Hudi
          Issue Type: Bug
            Reporter: Alexey Kudinkin


Any `DateFormat` based class is inherently NOT thread-safe.

Therefore we need to make sure we do concurrency-control (either through 
ThreadLocals or locks) when accessing these.


This has already bitten us w/ HUDI-2812.
