Subject [jira] [Updated] (HIVE-3709) Stop storing default ConfVars in temp file
Date Mon, 19 Nov 2012 19:41:58 GMT


Carl Steinbach updated HIVE-3709:

    Status: Open  (was: Patch Available)

@Kevin: I still see errors in TestHiveServerSessions when I run the test individually:

% ant clean package test -Dtestcase=TestHiveServerSessions

> 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.
