Hudson commented on HBASE-9003:
-------------------------------

FAILURE: Integrated in HBase-TRUNK-on-Hadoop-2.0.0 #830 (See [https://builds.apache.org/job/HBase-TRUNK-on-Hadoop-2.0.0/830/])

> This is the problem: {{TableMapReduceUtil#addDependencyJars}} relies on {{org.apache.hadoop.util.JarFinder}}
if available to call {{getJar()}}. However {{getJar()}} uses File.createTempFile() to create
a temporary file under {{hadoop.tmp.dir}}{{/target/test-dir}}. Due HADOOP-9737 the created
jar and its content is not purged after the JVM is destroyed. Since most configurations point
{{hadoop.tmp.dir}} under {{/tmp}} the generated jar files get purged by {{tmpwatch}} or a
similar tool, but boxes that have {{hadoop.tmp.dir}} pointing to a different location not
monitored by {{tmpwatch}} will pile up a collection of jars causing all kind of issues. Since
{{JarFinder#getJar}} is not a public API from Hadoop (see [~tucu00] comment on HADOOP-9737)
we shouldn't use that as part of {{TableMapReduceUtil}} in order to avoid this kind of issues.
