These > updates fire two step queries on each data node and both map and reduce > phases are executed in the sameĀ {{QUERY_POOL}} which can lead to deadlock > because reduce phase has blocking operation > {{GridReduceQueryExecutor#awaitAllReplies}}. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
