Is it ok to run hdfs balancer from namenode?
Here is the situation -
We added 30 new hosts to the cluster and our balancer wont finish. It has to be killed because we get errors in hbase when balancer runs. The errors are "Retries Exhausted" during inserts to hbase.
So, I am thinking of running balancer manually with higher threshold so that it completes then do subsequent runs lowering threshold.
Please let me know.
