Incorrect configuration: namenode address dfs.namenode.rpc-address is not configured

Question

I am getting this error when I try and boot up a DataNode. From what I have read, the RPC paramters are only used for a HA configuration, which I am not setting up (I think)

Answer 1

I too was facing the same issue and finally found that there was a space in fs.default.name value. truncating the space fixed the issue. The above core-site.xml doesn't seem to have space so the issue may be different from what i had. my 2 cents
