Continuous KeeperException and java.security.PrivilegedActionException: javax.security.sasl.SaslExc eption: GSS initiate failed

Dilan86 — Tue, 01 Mar 2022 17:51:04 GMT

We are using zookeeper-3.4.6.jar and hbase-client-1.4.5.jar for connecting to hbase cluster in a kerberized environment. All works fine except once in a while we get the following error.

ERROR ZooKeeperSaslClient:384 % An error: (java.security.PrivilegedActionException: javax.security.sasl.SaslException: GSS initiate failed [Caused by GSSException: No valid credentials provided (Mechanism level: Connection refused (Connectionrefused))]) occurred when evaluating Zookeeper Quorum Member's received SASL token. Zookeeper Client will go to AUTH_FAILED state

ERROR ClientCnxn:1015 % SASL authentication with Zookeeper Quorum member failed: javax.security.sasl.SaslException: An error: (java.security.PrivilegedActionException: javax.security.sasl.SaslException: GSS initiate failed [Caused by GSSException: No valid credentials provided (Mechanism level: Connection refused (Connection refused))]) occurred when evaluating ZookeeperQuorum Member's received SASL token. Zookeeper Client will go to AUTH_FAILED state

My concern is above error is not thrown to application level but only logged by the library.. So we can't do a retry in application level. In a case like above how can we do a retry for eg: create Connection again?

And after getting above error application goes to a state where below exception is logged continuously.

@Dilan86

Are you specifying a jaas.conf file for your application, through the java.security.auth.login.config property?

If so, could you please provide the configuration in it?

If not, create a file with your authentication details (principal and keytab) like the example below, save in a location that the application has access to and pass that property to the application using -Djava.security.auth.login.config=/path/to/jaas.conf

Client { com.sun.security.auth.module.Krb5LoginModule required useKeyTab=true keyTab="/path/to/appuser.keytab" storeKey=true useTicketCache=false principal="appuser@YOUR-REALM"; };

Cheers,

André

hi @araujo,

yes we are providing the jaas.conf

Client {

com.sun.security.auth.module.Krb5LoginModule required

debug = true

doNotPrompt = true

storeKey = true

useKeyTab = true

useTicketCache = false

principal = "tst@BK.DFN"

keyTab = "/etc/security/keytabs/tst.keytab"

serviceName = "zookeeper"

}

I don't think the issue is related to jaas.conf since application is working fine for most of the time. But we get the error below like in twice a month. After the below error application is not recovering.

Thanks.

@Dilan86 ,

If the application is not being affected and you only see this a few times a month, I wouldn't worry about it. It might be due to some intermittent issue, like network connectivity glitches, for example.

Unless it's hurting I would just ignore it.

Hi @araujo ,

The problem is after getting the error our application is not recovering. Do you have any suggestions on catching the below error in application and doing a retrying for connection?

Thanks

@Dilan86 ,

You can try enabling Kerberos debug log and waiting for it to happen again:

-Dsun.security.krb5.debug=true

What kind of applications is this?

Is it a long running application?

Have you noticed any patterns like "the application fails after running for x hours/days"?
