Subject [jira] Commented: (HIVE-812) Hive compiled with "ant package" should work with hadoop 0.17

Raghotham Murthy commented on HIVE-812:
---------------------------------------

It will make it longer to run tests only before commit. Its probably a good hit to take. We
can try to reduce the test time by using ant's parallel task -  http://ant.apache.org/manual/CoreTasks/parallel.html.

> The goal of shims is to make Hive compiled with "ant package" to work with any version
of hadoop.
> However currently it is not working with hadoop 0.17 for a minor issue:
> org.apache.hadoop.io.Text.compareTo was inherited (and NOT overriden) from org.apache.hadoop.io.BinaryComparable.compareTo
in hadoop 0.18 and above. When compiling Hive by default, we will compile it against hadoop
0.19.0. Java compiler will automatically replace org.apache.hadoop.io.Text.compareTo with
org.apache.hadoop.io.BinaryComparable.compareTo in some places, and that caused the problem.
