> Hi,
> Looking at the ExponentialBackOff Strategy for the apache curator I found
> this issue :
> @Override
> protected int getSleepTimeMs(int retryCount, long elapsedTimeMs)
> {
> // copied from Hadoop's RetryPolicies.java
> int sleepMs = baseSleepTimeMs * Math.max(1, random.nextInt(1 <<
> (retryCount + 1)));
> if ( sleepMs > maxSleepMs )
> {
> log.warn(String.format("Sleep extension too large (%d). Pinning
> to %d", sleepMs, maxSleepMs));
> sleepMs = maxSleepMs;
> }
> return sleepMs;
> }
> since sleepMs is an Integer and retryCount could be as large as 29 we could
> fall into an integer overflow case and therefore sleepMs being a negative
> number.
