Hi Stack, just to make clear, actually the connections to the zookeeper being kept are not on our mappers (tasktrackers) but on the client, which schedules the MR job i think, the mappers are just fine, as they are

Can you reuse Configuration instances though the "configuration" changes? Else in your Mapper#cleanup, call HTable.close() then try HConnectionManager.deleteConnection(table.getConfiguration()) after close (could be issue with executors used by multi* operations not completing before delete of connection finishes.
