Ashutosh Chauhan commented on HIVE-3664:
----------------------------------------
@Kanna, HIVE-2061 introduced this for backward compatibility reason. Currently,
user needs to *add* this jar in their script. So, if we don't create a symlink
user needs to update their script every time we upgrade a hive version, which
is not ideal. I am not sure what problem you are facing with symlinks on
Windows, but if that is not easily solvable one potential workaround would be
to check in build.xml that OS is windows and then not create symlink, but
instead copy hive-contrib-0.9.0 with name hive-contrib.jar. This will avoid
backward incompatibility as well as need to create symlink on Windows. But,
before we go down that path perhaps we should investigate more whats the
problem with symlinks on Windows.
> Avoid to create a symlink for hive-contrib.jar file in dist\lib folder.
