Do you see the same problem when you run export like this:
{code}
hbase org.apache.hadoop.hbase.mapreduce.Export ...

?
Export Utility throws ClassNotFoundException
Key: HBASE-6456
URL: https://issues.apache.org/jira/browse/HBASE-6456
Project: HBase
Issue Type: Bug
Components: mapred, mapreduce, util
Affects Versions: 0.96.0, 0.94.2
Reporter: Shengsheng Huang
Assignee: Shengsheng Huang
Priority: Minor
Attachments: HBASE-6456.patch
The command I ran is as below:
bin/hbase org.apache.hadoop.hbase.mapreduce.Driver export t1 ./t1
And I got the following exceptions:

This exception can be resolved by adding hbase common jar into
HADOOP_CLASSPATH. But this is an extra step for users and not so convenient.
We could add Bytes.class into dependency Jars of the MapReduce job.

I don't think this patch has something to do with these unit test. Also, those
test cases had passed at my local deployment.
