Make sure that value of kylin.hbase.client.keyvalue.maxsize (which resides in kylin config file - conf/kylin.properteis) and hbase.client.keyvalue.maxsize (which resides in hbase config file) are same. Usually we get Key value size too large error when value of kylin.hbase.client.keyvalue.maxsize greater than hbase.client.keyvalue.maxsize
