Hi,
I have a method in one of my classes that dumps out the system properties, and
that includes the Java path and it is showing this:
In listSystemProperties: [00001] java.class.path:
[/apps/accumulo-1.8.1/conf:/apps/accumulo-1.8.1/lib/accumulo-start.jar:/apps/accumulo-1.8.1/lib/slf4j-api.jar:/apps/accumulo-1.8.1/lib/slf4j-log4j12.jar:/apps/hadoop-2.7.3//share/hadoop/common/lib/log4j-1.2.17.jar:]
I think that that is a (maybe 'the') problem, i.e., the classpath when it
executes my code only has the Accumulo/hadoop JARs and the classpath doesn't
include any of the JARs that my code requires.
Is there a way that I can configure Accumulo so that when my Java code is
executed, that the classpath can include JARs that my code requires?
Also, I think there is another problem. The place where it is blowing up is in
my code, and it's inside a try-catch. And inside the catch, I output some
error messages to stdout, but that output does not appear in any of the logs
including the trc and err files. Why is that? And can I get the output of the
catch to output somewhere?
Thanks,
Jim

Hi,
Ok, I checked and there are .err and
.trc files.
The .err files are empty, but I do see
the stdout output from my classes in the
tserver_localhost.whatever.com.out.
So, it definitely is getting into my
code, but it looks like any errors are not showing up in the
.out file.

Josh and Ivan,
I don't have access to my test
environment now, but FYI, from the
stacktraces that I saw, I
can see that it actually got quite a
bit into my code, and
there was a lot of output (to stdout)
that was not in the
Accumulo logs or in the Accumulo
console output. I
will check later today about the
tserver files u mentioned
but I don't remember iseeing any .out
or .err files in the
logs directory? Do the .err and .out
files show up in
a different directory than the
Accumulo logs directory?

I would
expect that all output going to
stdout/stderr is being
captured in the tserver*.out or
tserver*.err files (or
master equivalents). Of course
if a
class is not being
loaded then it does not get much
of a
chance to output
anything....

Michael,I did use the "accumulo

and it shows all my JARs. Also
during

remembered -
I output a TON
of debug info in my JAR that I
added,
to stdout, but I
don't see any of that debug

the Accumulo

Accumulo logs. Is there a
way that I can have the debug

from my JAR show up
somewhere? That might
help...Thanks,Jim--------------------------------------------

AMYou can
use the classpath command to
help troubleshoot
as
well
$ACCUMULO_HOME/bin/accumulo
classpath

Putting the jars in the
lib/ext
directory is a perfectly
acceptable
mechanism. Make sure
your jars are in place
on all of your tservers before
you
start
them up. Perhaps this class is
being
found but is
failing to initialize itself
which can lead to
a
ClassNoDefError.
