Dan Berindei updated ISPN-4683:
-------------------------------
Priority: Critical (was: Major)
DefaultConsistentHash segment size is not not computed correctly
----------------------------------------------------------------
Key: ISPN-4683
URL:
https://issues.jboss.org/browse/ISPN-4683
Project: Infinispan
Issue Type: Bug
Security Level: Public(Everyone can see)
Components: Core, Remote Protocols
Affects Versions: 6.0.2.Final, 7.0.0.Beta1
Reporter: Dan Berindei
Assignee: Dan Berindei
Priority: Critical
Fix For: 7.0.0.Beta2
The segment size is computed using {{o.i.commons.util.Util.getSegmentSize()}} both on the
server and in the Java client. The computation uses {{float}} division, but {{float}}
precision is not good enough and sometimes the segments are too small (e.g. with 200
segments, the segment size is 10737418 instead of 10737419). This means the keys with a
hash of {{Integer.MAX_VALUE}} or {{-1}} are not properly mapped to a segment.
