Lars Hofhansl commented on HBASE-8140:
--------------------------------------
It looks like since this change
org.apache.hadoop.hbase.mapreduce.TestTableInputFormatScan has not passed a
single time in the EC2 builds (http://54.241.6.143/job/HBase-0.94/).
Change was introduced in Build #72, since then this tests times out (or doesn't
finish)
> TableMapReduceUtils#addDependencyJar fails when nested inside another MR job

> TableMapReduceUtils#addDependencyJar is used when configuring a mapreduce job
> to make sure dependencies of the job are shipped to the cluster. The code
> depends on finding an actual jar file containing the necessary classes. This
> is not always the case, for instance, when run at the end of another
> mapreduce job. In that case, dependency jars have already been shipped to the
> cluster and expanded in the parent job's run folder. Those dependencies are
> there, just not available as jars.
