Markus Jelsma commented on NUTCH-2978:
--------------------------------------
Ah yes, thanks! I am not sure if a 'solution' will come from Tika, that
specific package seems to be shaded in all versions between 2.3.0 and 2.6.0.
But, we, ASF Nutch, do not depend on it so we are good.
Patched like this, Nutch will fetch/parse just fine when running on Hadoop. I
did get this when doing an indexchecker using the job file:
{color:#000000}ERROR StatusLogger Log4j2 could not find a logging
implementation. Please add log4j-core to the classpath. Using SimpleLogger to
log to the console...{color}
{color:#000000}However, logging worked just fine.{color}
> Move to slf4j2 and remove log4j1 and reload4j

> I got in trouble upgrading some dependencies and got a lot of LinkageErrors
> today, or with a Tika upgrade, disappearing logs. This patch fixes that by
> moving to slf4j2, using the corrent log4j2-slfj4-impl2 and getting rid of old
> log4j -> reload4j.

> This patch fixes it.
