7th paragraph

The stated rule for replacing service principals is incorrect. Instead of:

[RULE]:[1:$1]((hdfs|yarn|hbase))s/.*/nobody/g

It should read:

[RULE]:[1:$1](hdfs|yarn|hbase)s/.*/nobody/

1st para (code snippet)

The code snippet contains two lines which have a duplication of "-provider". Specifically:

$ hadoop credentials create fs.s3a.access.key \ -value "ADKJFJXSCFG832QXSQNKQ" \
-provider -provider \ jceks://hdfs@nameservice1/user/ian/s3.jceks
$ hadoop credentials create fs.s3a.secret.key \ -value "fskQmOQPW/tY3BGbJC/kEosJJBTm2XI+Pk5pPxCK" \ -provider -provider \ jceks://hdfs@nameservice1/user/ian/s3.jceks

This should be:

$ hadoop credentials create fs.s3a.access.key \ -value "ADKJFJXSCFG832QXSQNKQ" \
-provider jceks://hdfs@nameservice1/user/ian/s3.jceks
$ hadoop credentials create fs.s3a.secret.key \ -value "fskQmOQPW/tY3BGbJC/kEosJJBTm2XI+Pk5pPxCK" \ -provider jceks://hdfs@nameservice1/user/ian/s3.jceks

That is, both instances of "-provider -provider \" should in fact be "-provider".
