Issues w/ M/R test cases if cache are not explicitly started on all nodes ------------------------------------------------------------------------- Key: ISPN-2835 URL: https://issues.jboss.org/browse/ISPN-2835 Project: Infinispan Issue Type: Feature Request Components: Core API, Distributed Execution and Map/Reduce Reporter: Ray Tsang Assignee: Galder Zamarreño Fix For: 5.3.0.Alpha1, 5.3.0.Final Attachments: mr-test-src.zip I ran into some issues while using M/R. The gist of the issue I was seeing is that: Start a cluster of Embedded Caches, like 4 nodes Put in 100 elements Run a simple M/R job to count the number of keys If I run the M/R job using the node I'm inserting elements into as coordinator - the result is 100 But if I run the M/R job using a different node as coordinator, the result is less than 100 More interestingly, I can pause for 5 seconds and run the M/R jobs again, the results are always less than 100 This behavior doens't occur if I explicitly run cacheManager.getCache() for each of the nodes...
