----------------------------------------
Summary: Allow configuration of the hash algorithm used by the
LogCleaner's offset map
Key: KAFKA-3987
URL: https://issues.apache.org/jira/browse/KAFKA-3987
Project: Kafka
Issue Type: Improvement
Components: config
Reporter: Luciano Afranllie
Priority: Minor
Fix For: 0.10.1.0
In order to be able to do deployments of Kafka that are FIPS 140-2
(https://en.wikipedia.org/wiki/FIPS_140-2) complaint one of the requirements is
not to use MD5.
Kafka is using MD5 to hash message keys in the offset map (SkimpyOffsetMap)
used by the log cleaner.
The idea is to be able to configure this hash algorithm to something allowed by
FIPS using a new configuration property.
The property could be named "log.cleaner.hash.algorithm" with a default value
equal to "MD5" and the idea is to use it in the constructor of CleanerConfig.
