--------------------------------------
Summary: custom jars for Hive query should be uploaded to scratch
dir per query; and/or versioned
Key: HIVE-6825
URL: https://issues.apache.org/jira/browse/HIVE-6825
Project: Hive
Issue Type: Improvement
Reporter: Sergey Shelukhin
Assignee: Sergey Shelukhin
Fix For: 0.14.0
Currently the jars are uploaded to either user directory or global, whatever is
configured, which is a mess and can cause collisions. We can upload to scratch
directory, and/or version.
There's a tradeoff between having to upload files every time (for example, for
commonly used things like HBase input format) (which is what is done now, into
global/user path), and having a mess of one-off custom jars and files,
versioned, sitting in .hiveJars.
