Summary: Function execution triggering internal exception Key: GEODE-10400 URL: https://issues.apache.org/jira/browse/GEODE-10400 Project: Geode Issue Type: Bug Components: native client Reporter: Mario Salazar de Torres *GIVEN* a cluster with at least 3 members *AND* a partitioned region with 1 redundant-copy *AND* a server function called *JustAFunction* with isHA=false, hasResult=true, optimizeForWrite=true *AND* a native client configured to connect to the above cluster with a pool using PR-Single-Hop=true *WHEN* *JustAFunction* is executed with onRegion and no filters *IF* the client has partial metadata due to the cluster starting up or a rebalance occurring *THEN* and exception of type *"org.apache.geode.internal.cache.execute.InternalFunctionInvocationTargetException: Multiple target nodes found for single hop operation"* is thrown by one of the servers --- *Additional information.* Currently, in geode-native whenever the metadata information is incomplete, and the user tries to execute the server function with onRegion and no filters, a request of type EXECUTE_REGION_FUNCTION_SINGLE_HOP is sent to each node. But the issue is that bucket partition used by the client is incorrect, leading consequently to the mentioned exception. *Potential solution.* The potential solution would be to detect that the metadata is incomplete before actually executing the function and send a EXECUTE_REGION_FUNCTION request to one of the cluster nodes instead. -- This message was sent by Atlassian Jira (v8.20.10#820010)
