> Key: HBASE-9003
> URL: https://issues.apache.org/jira/browse/HBASE-9003
> Project: HBase
> Issue Type: Bug
> Components: mapreduce
> Affects Versions: 0.92.2, 0.95.1, 0.94.9
> Reporter: Esteban Gutierrez
>
> 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.
