--------------------------------------
Summary: Speed up ant builds with the ant uptodate task
Key: HIVE-3449
URL: https://issues.apache.org/jira/browse/HIVE-3449
Project: Hive
Issue Type: Improvement
Components: Build Infrastructure
Affects Versions: 0.9.0
Reporter: Swarnim Kulkarni
Given that the hive build is an enormously loooong build (~ 6hrs), it might be
very helpful if there are some checkpointing capabilities available to be able
to resume a build from failed point and not have to restart everything on a
single test failure.
One possible way to do this would be to use the ant uptodate task to check set
of target files to be more up-to-date than given set of source files and
execute a target only if that is true.
By default this capability could be off but can be activated with the
-Dresume=true argument.
