> enablePerfMetrics was originally designed in BytesToBytesMap to control
> getNumHashCollisions getTimeSpentResizingNs getAverageProbesPerLookup.
> However, as the Spark version gradual progress. This parameter is only used
> for getAverageProbesPerLookup and always given to true when using
> BytesToBytesMap. it is also dangerous to determine whether
> getAverageProbesPerLookup opens and throws an IllegalStateException
> exception. So this pr will be remove enablePerfMetrics parameter from
> BytesToBytesMap. thanks.
