> There is a chance to see this error when write data to hudi with flink, and
> slot number per TM is larger than 1.
> java.lang.IllegalArgumentException: A metric named
> hudi_table1.lock.acquire.duration already exists
> The cause is in constructor of HoodieLockMetrics, when different thread from
> different slot of a Flink TM new HoodieLockMetrics, timer of identical
> metricName may registered to
> MetricRegistry multiple time, causing this error.

> we can add synchronized statement in function 'createTimerForMetrics' to make
> the test and set action atomic to avoid adding a timer multiple times.
