Sriram Subramanian commented on KAFKA-739:
------------------------------------------
1. OffsetMap
a. The way the probe is calculated, we could end up having the same probe
multiple times. Starting with attempt = hashSize - 4 to attempt = hashSize the
probe would be the same.
val probe = Utils.readInt(hash, math.min(attempt, hashSize-4)) +
math.max(0, attempt - hashSize)
2. LogCleaner
a. Cleaner doc comments need to be updated
Will look at the test changes and provide comments if any.
> Handle null values in Message payload
