[infinispan-issues] [JBoss JIRA] (ISPN-2181) Allow to inject the current cache into Mapper/Reducer/Callable objects

[Martin Gencur (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-2181?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12726850#comment-12726850 ] 

Martin Gencur commented on ISPN-2181:
-------------------------------------

We found out that the "current" cache cannot be injected into Reducer. It can be injected only to Mapper and Callable objects. This problem is described in ISPN-2404. If the description of this JIRA (ISPN-2181) is correct then ISPN-2404 is obviously a bug. Otherwise we should change title/description of this JIRA so that users know that injection of current cache is not supported for Reducer.

> Thanks to ISPN-1636, it is now possible to inject the cache into Mapper/Reducer/Callable objects however the cache injected is the default cache not the cache for which the MapReduceTask/DistributedExecutorService has been created which is quite error prone since we don't expect to get the default cache but the current cache.
