Enabling/disabling largish tables has always been problematic. We intend fixing it properly in the next major hbase but meantime we're patching what is currently in place, effectively the sending of a mesage across the cluster and then hoping rather than guaranteeing its received by all regionservers and that there are no issues during the enable/disable. You could try being extra careful. On disable, ensure all are offline before proceeding. This probably requires manual inspection of meta region (region gets status=offline feature when disabled successfully) for now. 0.20.4 which has improvements that particularly address this issue should be out soon also. Meantime, its probably best to do as little enable/disable as possible. St.Ack
