Subject [jira] [Commented] (ACCUMULO-1339) log4j jar is required to be in a specific place
Date Sun, 19 May 2013 01:51:15 GMT


Christopher Tubbs commented on ACCUMULO-1339:

What's the progress on this?

* Is it still a problem?
* Where else can the jar be found, if not the places we look?
* How else can we find it?
* What's the risk of including it?

> We are no longer packaging log4j, and it needs to be on our classpath before the classloader
can read modifications to general.classpaths in the accumulo-site.xml file.  Line 84 of the
accumulo script looks for the log4j in two possible hadoop subdirectories, but if it isn't
in either of those accumulo init will not run (thanks to [~vines] for tracking this down).

> If we can't come up with a reasonable way to address the issue, we should at least document
that the log4j jar must exist in one of those locations.
