Kerberos Encryption Types : des3-cbc-sha1 (default rc4-hmac) 

Anyone have any suggestions how to resolve this problem?

[#2]

Has anyone managed to resolve this? I'm facing the same issue

[#3 · Accepted solution]

Hi Jason,

This might be due to the mismatch of encryption types between clients and the KDC server. Please follow the below steps and see if it helps.

1. Stop the cluster through CM
2. Go to CM --> Administration --> Kerberos --> 'Kerberos Encryption Types', then add the following encryption types:

des3-hmac-sha1
arcfour-hmac
des-hmac-sha1
des-cbc-md5
des-cbc-crc

3. Do redeploy krb5.conf through CM, and restart the cluster.

Daisuke

[#4]

The suggestion from Daisuke could be teh solution,

When you forget to install the JCE you will see messages like:

INFO org.apache.hadoop.ipc.Server: IPC Server listener on 8022: readAndProcess threw exception javax.security.sasl.SaslException: GSS initiate failed [Caused by GSSException: Failure unspecified at GSS-API level (Mechanism level: Encryption type AES256 CTS mode with HMAC SHA1-96 is not supported/enabled)] from client 127.0.0.1. Count of bytes read: 0

  at com.sun.security.sasl.gsskerb.GssKrb5Server.evaluateResponse(GssKrb5Server.java:159)

You can see more details in the kerberos security logs using this startup parameter:

HADOOP_OPTS="-Dsun.security.krb5.debug=true" 

Greetings,

Alexander Bij

hi Daisuke,

 your steps solved my problem.

thanks

Hi Jason,

I was also facing the same issue of impala services not starting after enabling kerberos. I did added the kerberos authentication types as you suggested but that didn't resolved the problem.

Hi Cibi,

What is your 'kerberos_reinit_interval' flag set to?

Also, do you see this only with the catalogd or even with the statestored and impalad?

- Sailesh

[#8]

Hi Sailesh,

My kerberos renewable lifetime is set to 7 days.

Kerberos ticket validity is 10 hours after which it gets expired.

I'm getting this error only in Catalog server and not in Statestore.

Error:

statestore registration unsuccessful: RPC Error: No more data to read.
RPC Error: No more data to read.

Thanks,

Cibi

[#9]

Hi Cibi,

There is a 'renewable_lifetime' option in the krb5.conf file and a 'kerberos_reinit_interval' Impala startup flag. Which one are you looking at?

[#10]

Hi Sailesh,

I have the renewable_lifetime value set to 604800, but i don't have a 'kerberos_reinit_interval' Impala startup flag parameter set anywhere.

Does the flag need to be set for Impala in krb5.conf file?

PFB the krb5.conf file contents.
