Hi folks, I noticed hdfs.headless.keytab only exists on NameNode and HDFS client node.
Could someone please share some details on why DN does not need the hdfs.headless.keytab ? I thought we need it in order for DN to work against NN. Any negative impacts if I always include hdfs.headless.keytab on the DN nodes (such as ensure HDFS client always cohost with DNs) ? Thank you. Di
