> On large cluster, replace-datanode-on-failure should be set to true, but on
> small clusters (developers environment or testing environment), it should be
> set to false, otherwise, if datanodes are overloaded, it will report error.
> This is the reason it was set to false by default earlier.
> Ambari should set it to true when cluster size > 4, otherwise set it to false.
