[GitHub] [spark] gaborgsomogyi opened a new pull request #26252:
[SPARK-29580][TESTS] Add kerberos debug messages for Kafka secure tests
gaborgsomogyi opened a new pull request #26252: [SPARK-29580][TESTS] Add kerberos debug messages for Kafka secure tests
URL: https://github.com/apache/spark/pull/26252
### What changes were proposed in this pull request?
`org.apache.spark.sql.kafka010.KafkaDelegationTokenSuite` failed lately. After had a look at the logs it just shows the following fact without any details:
```
Caused by: sbt.ForkMain$ForkError: sun.security.krb5.KrbException: Server not found in Kerberos database (7) - Server not found in Kerberos database
```
Since the issue is intermittent and not able to reproduce it we should add more debug information and wait for reproduction with the extended logs.
### Why are the changes needed?
Failing test doesn't give enough debug information.
### Does this PR introduce any user-facing change?
No.
### How was this patch tested?
I've started the test manually and checked that such additional debug messages show up:
```
