MassIndexer is not ClusteredQuery friendly ------------------------------------------ Key: ISPN-4822 URL: https://issues.jboss.org/browse/ISPN-4822 Project: Infinispan Issue Type: Bug Components: Embedded Querying Affects Versions: 7.0.0.CR1 Reporter: Gustavo Fernandes Assignee: Gustavo Fernandes Fix For: 7.1.0.CR1 The MassIndexer assumes a cluster-wide shared index, and thus calls wipeExistingIndexes() only once in the node where it is invoked, the same apply for flush operation after the all mappers and reducers run. When using Clustered Queries, indexes are locally scoped and independent , and need to be wiped and flushed on every node.
