Suresh Srinivas commented on HDFS-1998:
---------------------------------------
# Could you please add a unit test for the new method.
# Why are you printing empty string as error in NNRpcAddressesCommandHandler?
# Command description "name node" to "namenode"
# In the script you are setting errorFlag before for loop. But you are not
using that value and still enter for loop?
> make refresh-namodenodes.sh refreshing all namenodes

> refresh-namenodes.sh is used to refresh name nodes in the cluster to check
> for updates of include/exclude list. It is used when decommissioning or
> adding a data node. Currently it only refreshes the name node who serves the
> defaultFs, if there is defaultFs defined. Fix it by refreshing all the name
> nodes in the cluster.
