    <description>&lt;P&gt;Thanks.  Sorry I didn't know what log to look in.  Ranger and KMS is not my forte.   &lt;/P&gt;&lt;P&gt;Thanks, &lt;A rel="user" href="https://community.cloudera.com/users/47/vperiasamy.html" nodeid="47"&gt;@vperiasamy&lt;/A&gt; for contributing to the effort. &lt;/P&gt;</description>

It is apparently not pointing to the correct location. &lt;/P&gt;</description>

      <description>&lt;P&gt;I followed this &lt;A href="https://community.hortonworks.com/content/supportkb/151796/error-orgapachehadoopsecurityauthenticationclienta.html"&gt;article&lt;/A&gt;.  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.&lt;/P&gt;</description>

      <description>&lt;P&gt;So it's part of the question.  I found the logs&lt;/P&gt;&lt;P&gt;/var/log/hadoop-kms/kms-localhost.2018-01-31.log&lt;/P&gt;&lt;PRE&gt;Caused by: java.lang.IllegalArgumentException: Invalid rule: hdfs/ip-172-31-10-196.us-west-2.compute.internal@MYREALM.INTERNAL,
        spark/ip-172-31-10-196.us-west-2.compute.internal@MYREALM.INTERNAL,
        yarn/ip-172-31-10-196.us-west-2.compute.internal@MYREALM.INTERNAL,
        HTTP/ip-172-31-10-196.us-west-2.compute.internal@MYREALM.INTERNAL

        at org.apache.hadoop.security.authentication.server.KerberosAuthenticationHandler.init(KerberosAuthenticationHandler.java:210)
        ... 31 more&lt;BR /&gt;&lt;/PRE&gt;&lt;P&gt;Looks like my rules that were badly written caused the issue.&lt;/P&gt;</description>

      <description>&lt;P&gt;Thanks.  Sorry I didn't know what log to look in.  Ranger and KMS is not my forte.   &lt;/P&gt;&lt;P&gt;Thanks, &lt;A rel="user" href="https://community.cloudera.com/users/47/vperiasamy.html" nodeid="47"&gt;@vperiasamy&lt;/A&gt; for contributing to the effort. &lt;/P&gt;</description>

      <description>&lt;P&gt;Can you check you &lt;STRONG&gt;hadoop.kms.authentication.kerberos.name.rules &lt;/STRONG&gt;settings from kms-site.xml? Try "DEFAULT" if you have a customized setting that is invalid.&lt;/P&gt;&lt;P&gt;You mentioned that the kms principle is changed. Can you also post your &lt;STRONG&gt;hadoop.kms.authentication.kerberos.principal &lt;/STRONG&gt;and &lt;STRONG&gt;hadoop.security.auth_to_local&lt;/STRONG&gt; settings from core-site.xml?&lt;/P&gt;</description>
