Create

with Hadoop - hadoop client utility

hadoop archive -archiveName name -p <parent> [-r <replication factor>] <src>* <dest>

Unarchive

Since all the fs shell commands in the archives work transparently, unarchiving is just a matter of copying.

To unarchive:

• sequentially (with HDFS - hdfs command line)

hdfs dfs -cp har:///user/zoo/foo.har/dir1 hdfs:/user/zoo/newdir

• in parallel, with DistCp:

hadoop distcp har:///user/zoo/foo.har/dir1 hdfs:/user/zoo/newdir
