why I got error "Could not retrieve endpoint rangs" when I run sstableloader?

[土卜皿]

hi, all
   I used the sstableloader many times successfully, but I got the
following error:

[root@localhost pengcz]# /usr/local/cassandra/bin/sstableloader -u user -pw
password -v -d 172.21.0.131 ./currentdata/keyspace/table

Could not retrieve endpoint ranges:

I don't know whether this error is relative to one of cluster nodes' linux
crash?

Any advice will be appreciated!
