So it's part of the question. I found the logs /var/log/hadoop-kms/kms-localhost.2018-01-31.log Caused by: java.lang.IllegalArgumentException: Invalid rule: hdfs/ip-172-31-10-196.us-west-2.compute.internal@MYREALM.INTERNAL,

I followed this article. It tell you how to configure KMS. That is what I followed immediately before getting the 404. Is it possible that by following that aricle I'm making KMS crash and hence the 404? How would I look at the error log for KMS. It seems to be a web app but I can't seem to find a log for it.

The message is odd, after changing the principle of KMS Authentication failed, status: 404, message: Not Found Any hints of where to look would be appreciated.. .there isn't anything in the KDC log: Jan 31 14:49:54 ip-172-31-11-134.us-west-2.compute.internal krb5kdc[9279](info): TGS_REQ (2 etypes {18 17}) 172.31.10.196: ISSUE: authtime 1517428183, etypes {rep=18 tkt=18 ses=18}, spark_remote/ip-172-31-10-196.us-west-2.compute.internal@DATAPASSPORT.INTERNAL for yarn/ip-172-31-10-196.us-west-2.compute.internal@MYREALM.INTERNAL

Created symlink of ranger kms conf to core site and hdfs site is a vagues statement. Could you explain a little more... I know how to create a symlink, but I don't know what you mean by "Created symlink of ranger kms conf to core site and hdfs site"
