Lars Hofhansl commented on HBASE-9165:
--------------------------------------
The reason is probably this from the logs:
{code}
2013-11-16 17:57:00,896 DEBUG [pool-1-thread-1]
mapreduce.TableMapReduceUtil(665): For class
org.apache.hadoop.hbase.util.Bytes, using jar
/x1/jenkins/jenkins-slave/workspace/HBase-0.94/trunk/target/test-dir/hadoop-1223249546787952422.jar
{code}
This does not happen on my local box.

> The way we support adding HBase dependencies to a MapReduce job in
> {{TableMapReduceUtils#addDependencyJars(job)}} is a bit monolithic. Advanced
> users need a way to add HBase and its dependencies to their job without us
> snooping around for ouput formats and the like (see PIG-3285). We can also
> benefit from a little more code reuse between our {{mapred}} and
> {{mapreduce}} namespaces.
