getReplicationMapping

public java.util.Map<java.lang.Integer,java.util.HashMap<java.lang.Integer,java.util.List<java.lang.Integer>>> getReplicationMapping(int restoringNode,
                                                                                                                                     Cluster cluster,
                                                                                                                                     StoreDefinition storeDef)

For a particular node, finds out all the [replica, partition] tuples it needs to steal in order to be brought back to normal state

Parameters:

restoringNode - The id of the node which needs to be restored

cluster - The cluster definition

storeDef - The store definition to use

Returns:

Map of node id to map of replica type and corresponding partition list

For a particular node, finds out all the [replica, partition] tuples it needs to steal in order to be brought back to normal state

Parameters:

restoringNode - The id of the node which needs to be restored

cluster - The cluster definition

storeDef - The store definition to use

zoneId - zone from which nodes are chosen, -1 means no zone preference

Returns:

Map of node id to map of replica type and corresponding partition list
