-----------------------------------
Summary: Kafka does not provide any default value for
kafka.log.dirs and creates confusion / poor UX
Key: AMBARI-8173
URL: https://issues.apache.org/jira/browse/AMBARI-8173
Project: Ambari
Issue Type: Bug
Components: ambari-agent, ambari-web, stacks
Affects Versions: 1.7.0
Reporter: Yusaku Sako
Assignee: Yusaku Sako
Priority: Critical
Fix For: 1.7.0
Kafka does not provide any default value for log.dirs property.
The user is prompted to enter a path (or paths) there.
If the user enters paths that kafka user cannot create, then Kafka Broker fails
to come up and Kafka Service Check fails Once the user goes to the dashboard,
most of the services show up red as the start operation for other components
were canceled .
There are several problems with this.
1. Most users will install the full stack including Kafka. The user does not
know what directory/directories to put there (and does not want to be concerned
about that at install time). We specify default directories for all other
components so we should do the same.
2. If we leave this blank, then the user is force to enter something. I put
/kafka. However, Ambari agent does not try to create/chown/chmod, so Kafka
tries to create the directory as "kafka" user and this fails and you end up
getting a dashboard with a bunch of services down. Even if we provide some
default and the user changes it, the same failure occurs. So Ambari agent
should automatically take care of directory creation/chown/chmod.
