Todd Lipcon commented on HIVE-487:
----------------------------------
Patch looks good for me (just inspected it visually over here)
One question: once we use these shims, is it possible that we could have just a
single hive distribution which works for all versions of Hadoop? I think we may
be able to accomplish this by making the shim jar output be
libs/shims/hive_shims-{$hadoop.version.prefix}.jar. Then either through
ClassLoader magic or shell wrapper magic, we put the right one on the classpath
at runtime based on which hadoop version is on the classpath.
Is this possible? Having different tarballs of hive for different versions of
hadoop makes our lives slightly difficult for packaging.
