[infinispan-issues] [JBoss JIRA] Commented: (ISPN-1275) Virtual nodes producing same hash id for two different cluster nodes
[
https://issues.jboss.org/browse/ISPN-1275?page=com.atlassian.jira.plugin....
]
Manik Surtani commented on ISPN-1275:
-------------------------------------
One way to minimise the scope of the problem, even with virtual nodes, is to increase the
hash space (perhaps to Integer.MIN_VALUE ~ Integer.MAX_VALUE rather than 0 ~ 10000 or
whatever we have right now).
But it still doesn't solve it completely.
Virtual nodes producing same hash id for two different cluster nodes
--------------------------------------------------------------------
Key: ISPN-1275
URL: https://issues.jboss.org/browse/ISPN-1275
Project: Infinispan
Issue Type: Bug
Components: Distributed Cache
Affects Versions: 5.0.0.CR8
Reporter: Galder Zamarreño
Assignee: Manik Surtani
Priority: Blocker
Fix For: 5.0.0.FINAL
Attachments: hashids.log
While working on ISPN-1273, I've discovered that when virtual nodes are enabled,
ConsistentHash.getHashIds(address) can return the same hash for two different cluster
nodes. Example: with 500 virtual nodes, both NodeA-23181 and NodeB-39177 produce hash id
*5289*. See attached log.
