RowCounter at least works for me. Its odd that you are 26% of the ways through the map task when this happens (Is this so w/ rowcounter?). That would almost imply the problem transient since a bunch of map tasks have completed already. What if you added a bit of debug to TIF#setConf and see what its passing into setHTable. St.Ack
