KERBEROS issues - HDFS cluster
Hi , We’ve implemented Kerberos in our hadoop cluster, but we are having issues with our pipelines. We are getting this error 🙂 "Reason: org.apache.hadoop.security.AccessControlException: SIMPLE authentication is not enabled. Available:[TOKEN, KERBEROS] " “Caused by: java.util.concurrent.ExecutionException: org.apache.hadoop.security.AccessControlException: SIMPLE authentication is not enabled. Available:[TOKEN, KERBEROS] at java.util.concurrent.FutureTask.report(FutureTask.java:122) at java.util.concurrent.FutureTask.get(FutureTask.java:206) at com.snaplogic.snap.api.binary.SimpleReader.doRead(SimpleReader.java:332) … 30 more Caused by: org.apache.hadoop.security.AccessControlException: SIMPLE authentication is not enabled. Available:[TOKEN, KERBEROS] at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:62” All was configured correctly , keytabs are ok, i’m able to do a kinit from any groundplex nodes, time on KDC servers and kerberos clients is synced. Pipelines worked ok for some while, but we saw that after we restarted jcc process on the groundplex nodes pipelines started to fail. JCE extension was installed as per https://docs-snaplogic.atlassian.net/wiki/spaces/SD/pages/2015960/How+to+Configure+a+Groundplex+for+CDH+with+Kerberos+Authentication Any ideas ?

Hello, Very often i see this error (“Unable to reach Snaplex neighbor - https://hostname:8081”) on the Snaplogic Control Pane, on Dashboard on the groundplex servers. Port 8081 is open between nodes and there are no fw issues. The problem is that when i’m accessing directly the node URL, https://hostname:8081 , i see that all the Neighbors are green and communicates with all of them. Why is this alert showing on the Snaplogic Dashboard ? Is there any parameter ( heartbeat config or something similar) that i can change on my nodes ? Thank you, Petrica4.5KViews0likes2CommentsRe: SSO login issues
I’m using same metadata on all organizations. What i’ve done is that i’ve just changed metadata on one org, but afterwards i’ve reverted back , but error is still there. Is like something is stuck on the backend of the snaplogic portal and is still seeing that organization with different IdP metadata.3.4KViews0likes1Comment
