> PreemptiveFastFailInterceptor do not set fastFailClearingTimeMilliSec, so in
> occasionallyCleanupFailureInformation function this branch
> {code:java}
> else if (now > entry.getValue().timeOfFirstFailureMilliSec

> will be always be true,then the repeatedFailuresMap will be clean.
> and in the constructor function
> {code:java}
> public PreemptiveFastFailInterceptor(Configuration conf) {
> this.fastFailThresholdMilliSec = conf.getLong(
> HConstants.HBASE_CLIENT_FAST_FAIL_THREASHOLD_MS,
> HConstants.HBASE_CLIENT_FAST_FAIL_THREASHOLD_MS_DEFAULT);
> this.failureMapCleanupIntervalMilliSec = conf.getLong(
> // this constant seem to set fastFailClearingTimeMilliSec, it may be a
> mistake.
> HConstants.HBASE_CLIENT_FAST_FAIL_CLEANUP_MS_DURATION_MS,
> HConstants.HBASE_CLIENT_FAST_FAIL_CLEANUP_DURATION_MS_DEFAULT);
