-----------------------------------
Summary: Stop storing default ConfVars in temp file
Key: HIVE-3709
URL: https://issues.apache.org/jira/browse/HIVE-3709
Project: Hive
Issue Type: Improvement
Components: Configuration
Affects Versions: 0.10.0
Reporter: Kevin Wilfong
Assignee: Kevin Wilfong
To work around issues with Hadoop's Configuration object, specifically it's
addResource(InputStream), default configurations are written to a temp file (I
think HIVE-2362 introduced this).
This, however, introduces the problem that once that file is deleted from /tmp
the client crashes. This is particularly problematic for long running services
like the metastore server.
Writing a custom InputStream to deal with the problems in the Configuration
object should provide a work around, which does not introduce a time bomb into
Hive.
