just a heads up about unbalanced HDFS. While productionizing “HDFS balancing” was discussed some weeks back, it seems other tasks took priority. Getting balancing in place before the weekend might spare you nodes getting unhealthy over the weekend (and all the issues that are chained to that).
Have fun, Christian
