Sylvain Lebresne commented on CASSANDRA-3673:
---------------------------------------------

Adding a --skip-dead-nodes options doesn't seem unreasonable at all to me, if that is what we're talking about.

> Below are some of the issues I have been facing since I am using sstable-loader cassandra utility in cassandra-0.8.2
> 1) We have configured the sstableloader on a different machine.Since we have loaded sstables from this machine it has become a part of the cluster and except loading time it is always unreachable in describe cluster.
>     a)As it is unreachable whenever I changes the schema it says this node is unreachable(but its ok as schema change reflect over the other nodes)
>     b) The main problem is when I tried to remove the node out of the cluster using nodetool removetoken ,the process stucks saying "RemovalStatus: Removing token (62676456546693435176060154681903071729). Waiting for replication confirmation from [cassandra-1/(10.10.01.10)(This is the ip of loader machine)]".As loader is part of the cluster and cassandra tries to stream the data from loader machine and could not stream.
> So instead of making loader machine permanent part of the cluster can we make it temporarily part of the cluster?
> 2)When any of the node is down or unreachable with thrift based client like pelop we can insert the data into the cassandra cluster.But this is not the case with the sstable-loader.It do not work(do not stream) when any of the nodes in the cluster is down or unreachable.
