Jobs failing with ClassNotFoundException
Chris Sigman 2013-02-14, 18:41
Hi everyone,

I've got a job I'm running that I can't figure out why it's failing.  I've
tried running jobs from the examples, and they work just fine.  I'm running
the job via

> ./bin/tool.sh ~/MovingAverage.jar movingaverage.MAJob inst namenode root
pass stockdata movingaverage

which I see is running the following exec call that seems perfect to me:

exec /usr/lib/hadoop/bin/hadoop jar /MovingAverage.jar movingaverage.MAJob
-libjars "/opt/accumulo/lib/libthrift-0.6.1.jar,/opt/accumulo/lib/
accumulo-core-1.4.2.jar,/usr/lib/zookeeper//zookeeper-3.3.
5-cdh3u5.jar,/opt/accumulo/lib/cloudtrace-1.4.2.jar,/opt/
accumulo/lib/commons-collections-3.2.jar,/opt/accumulo/lib/commons-
configuration-1.5.jar,/opt/accumulo/lib/commons-io-1.4.
jar,/opt/accumulo/lib/commons-jci-core-1.0.jar,/opt/
accumulo/lib/commons-jci-fam-1.0.jar,/opt/accumulo/lib/
commons-lang-2.4.jar,/opt/accumulo/lib/commons-logging-
1.0.4.jar,/opt/accumulo/lib/commons-logging-api-1.0.4.jar" inst namenode
root pass tmpdatatable movingaverage

but when the job runs, it gets to the map phase and fails:

13/02/14 13:25:26 INFO mapred.JobClient: Task Id :
attempt_201301171408_0293_m_000000_0, Status : FAILED

I've also tried hacking it to work by adding the accumulo-core jar to
hadoop's lib dir, but that doesn't seem to work either.

Thanks for any help,
