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

Answer 2

in my case, I have wrongly set HADOOP_CONF_DIR to an other Hadoop installation.

Add to hadoop-env.sh:

export HADOOP_CONF_DIR=/usr/local/hadoop/etc/hadoop/

Answer 3

check the core-site.xml under $HADOOP_INSTALL/etc/hadoop dir. Verify that the property fs.default.name is configured correctly

Answer 4

Configuring the full host name in core-site.xml, masters and slaves solved the issue for me.

Old: node1 (failed)

New: node1.krish.com (Succeed)

Answer 5

Add the below line in hadoop-env.cmd

set HADOOP_HOME_WARN_SUPPRESS=1

Answer 6

Check your '/etc/hosts' file:
There must be a line like below: (if not, so add that)
namenode 127.0.0.1
Replace 127.0.01 with your namenode IP.
