Ben Podgursky commented on HADOOP-10101:
----------------------------------------
I've been lurking on these Guava tickets for while a while, and I just want to
chime in to say I'm going to be incredibly disappointed if this gets reverted.
The number of watchers on this ticket should be an indicator in itself, and I'm
sure for every person who bothered creating a jira account, there are a couple
hundred who were bitten by this.
Has anyone contacted the maintainers on the major affected downstream projects
like Spark and HBase? My guess is that they would be more than happy to help
work around any breakages this upgrade causes -- if they are like us, they
would be overjoyed at being able to finally upgrade.
Hadoop's ancient Guava dependency is the single largest issue we run into when
putting any other third party jar on our client or task classpath. There are
many libraries developed outside the Hadoop ecosystem which (rightfully) assume
they can use a newer version of Guava, and we regularly either have to do
horrible hacks to get these onto the client classpath, or tell developers not
to use them. This is an incredible time-waster that shouldn't exist.
I understand the concerns about stability, but this is a major upgrade, no? I
don't think it's acceptable to say that Hadoop will be running Guava 11 until
Hadoop 4 comes out in 2025.
