[jira] [Created] (ZOOKEEPER-3743) Poor error messages about the
parsing of the jass.conf file
Alexandre Anouthcine created ZOOKEEPER-3743:
-----------------------------------------------
Summary: Poor error messages about the parsing of the jass.conf file
Key: ZOOKEEPER-3743
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3743
Project: ZooKeeper
Issue Type: Improvement
Affects Versions: 3.5.6
Environment: Debian 10
Reporter: Alexandre Anouthcine
I'm trying to set up a cluster of 3 Zookeeper nodes and I'm struggling to understand the error messages regarding jaas.conf file.
I found 2 articles about the [Server-Server mutual authentication|[https://cwiki.apache.org/confluence/display/ZOOKEEPER/Server-Server+mutual+authentication]]
jaas.conf file are the same on 3 nodes and it seems to be working:
|{{QuorumServer {}}
{{ org.apache.zookeeper.server.auth.DigestLoginModule required}}
{{ user_zkinternal="pa$$word";}}
{{};}}
{{ }}
{{QuorumLearner {}}
{{ org.apache.zookeeper.server.auth.DigestLoginModule required}}
{{ username="zkinternal"}}
{{ password="pa$$word";}}
{{};}}|
Now I want to connect a Solr client to it. I found an article about [Client-Server mutual authentication|[https://cwiki.apache.org/confluence/display/ZOOKEEPER/Client-Server+mutual+authentication]]
It show an example:
|{{Server {}}
{{ org.apache.zookeeper.server.auth.DigestLoginModule required}}
{{ }}{{user_super=}}{{"adminsecret"}}
{{ }}{{user_bob=}}{{"bobsecret"}}{{;}}
{{};}}|
The problem when I try to change my original jaas.conf file with something else like:
|{{QuorumServer {}}
{{ org.apache.zookeeper.server.auth.DigestLoginModule required}}
{{ user_zkinternal="pa$$word";}}
{{ user_solr=}}{{"solrsecret"}}{{;}}{{}}
{{};}}
{{ }}
{{QuorumLearner {}}
{{ org.apache.zookeeper.server.auth.DigestLoginModule required}}
{{ username="zkinternal"}}
{{ password="pa$$word";}}
{{};}}|
or
|{{QuorumServer {}}
{{ org.apache.zookeeper.server.auth.DigestLoginModule required}}
{{ user_zkinternal="pa$$word";}}{{}}
{{};}}
{{ }}
{{QuorumLearner {}}
{{ org.apache.zookeeper.server.auth.DigestLoginModule required}}
{{ username="zkinternal"}}
{{ password="pa$$word";}}
{{};}}
{{}}
{{}}
{{Server {}}
{{ org.apache.zookeeper.server.auth.DigestLoginModule required}}
{{user_solr=}}{{"solrsecret"}}{{;}}{{}}
{{};}}|
or even
|{{QuorumServer {}}
{{ org.apache.zookeeper.server.auth.DigestLoginModule required}}
{{ user_zkinternal="pa$$word"}}{{}}{{}}
{{};}}
{{ }}
{{QuorumLearner {}}
{{ org.apache.zookeeper.server.auth.DigestLoginModule required}}
{{ username="zkinternal"}}
{{ password="pa$$word";}}
{{};}}|
(Notice the missing semicolon for the user)
I always get the same error message which doesn't make much sense to me:

So what does it mean ? How to do it ?
