--------------------------------------------

             Summary: Kafka service failed to start during regenerate keytab after upgrade from Biginsights 4.2.5,4.2.0 to HDP 2.6.2
                 Key: AMBARI-21573
                 URL: https://issues.apache.org/jira/browse/AMBARI-21573
             Project: Ambari
          Issue Type: Bug
          Components: express-upgrade
    Affects Versions: 2.5.2
            Reporter: Alejandro Fernandez
            Assignee: Alejandro Fernandez
            Priority: Blocker
             Fix For: 2.5.2


*Steps to Reproduce*
# Install IOP 4.2.5 with Kafka
# Kerberize the cluster
# Upgrade Ambari to 2.5.2
# Register HDP 2.6
# Remove iop-select
# Install HDP 2.6.
# Express Upgrade from BigInsights to HDP
# Regenerate Keytab

After regenerate keytab, Kafka will go down.

The problem is that kafka-broker config type has 
{noformat}
listeners: "SASL_PLAINTEXT://localhost:6667"
security.inter.broker.protocol: "SASL_PLAINTEXT"
{noformat}

and it needs to replace "SASL_PLAINTEXT" with "PLAINTEXTSASL"
