I am running StreamSets in Cluster Batch mode, however, I just discovered that everyday, there are multiple directories created in the /tmp directory named hadoop-unjar<some_id_I_am_not_sure>. What are they? Can I delete them?

These directories are actually created by the hadoop jar command, rather than StreamSets Data Collector. See this email on the hadoop-user list for more details.

Given that they are in the /tmp directory, they should be safe to delete.
