Zheng Shao commented on HIVE-812:
---------------------------------
I ran the tests in the following order, and it all passed:
{code}
ant clean package
ant test -Dhadoop.version=0.17.2.1
ant test -Dhadoop.version=0.18.3
ant test -Dhadoop.version=0.19.0
ant test -Dhadoop.version=0.20.0
{code}
We are already running tests in parallel using a little different way. The test
for one hadoop version takes around 18 minutes with 4 parallel tests, on a
machine with 16GB memory and 4 cpu cores.
> Hive compiled with "ant package" should work with hadoop 0.17

> 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.
