Egil Sorensen commented on HADOOP-7810:
---------------------------------------
@Owen - The use case is for a storing from a Pig script using HCatalog's
dynamic partitioning and with HAR enabled.
Correct, the HarFileSystem is in the classpath.
But a call like the above fails with a ClassNotFoundException on
org.apache.hadoop.tools.HadoopArchives$HArchiveInputFormat.
Therefore the suggestion to move the HadoopArchieves classes from hadoop_tools
jar, which is not in `hadoop classpath`, into the hadoop-core jar. (The same
jar that holds the HarFileSystem class.)

> "The HadoopArchieves classes are included in the
> $HADOOP_HOME/hadoop_tools.jar, but this file is not found in `hadoop
> classpath`.
> A Pig script using HCatalog's dynamic partitioning with HAR enabled will
> therefore fail if a jar with HAR is not included in the pig call's '-cp' and
> '-Dpig.additional.jars' arguments."
> I am not aware of any reason to not include hadoop-tools.jar in 'hadoop
> classpath'. Will attach a patch soon.
