Subject [jira] [Commented] (ACCUMULO-3631) Exclude 'slf4j' artifacts from classpath in default value for general.classpaths
Date Tue, 03 Mar 2015 00:47:07 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-3631?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14344173#comment-14344173

Josh Elser commented on ACCUMULO-3631:
--------------------------------------

bq. this issue has shown that one can hit the default value in cases where one has taken care
to change the defaults in the configuration files

That is a rather obvious case that I (shamefully) didn't consider.

bq. I'm reluctant to phrase my concerns as "blocker"

Sorry, didn't mean to put words in your mouth. Just meant to encapsulate your concerns.

I'll modify the default value in 1.6 to remove the addt'l entries and leave 1.7 be. Where
exactly do you think aforementioned documentation should exist [in the user manual] (?). http://accumulo.apache.org/1.6/accumulo_user_manual.html#_accumulo_settings
?

> Was testing out some Ambari integration for Accumulo that [~billie.rinaldi] and [~mwaineo]
have been working on (AMBARI-5265) and found that, despite accumulo-site.xml having jars starting
with slf4j excluded from the classpath, the shell would complain about duplicate slf4j-log4j12
jars on the classpath.
> Turns out, because access to accumulo-site.xml was restricted (and we only had client.conf
to use), we fell back on the default value for general.classpaths defined in AccumuloClassLoader.
A short-term fix is to update the value there to match what's in our site template.
> I'll add another issue for a long term fix to add classpath support to client configuration.
