Just a heads up we are finishing up work on a 3.3 WIP, so please give it a spin.
For the most part, there are improvements to the Hadoop/Tez PartitionTap that make it much more reliable when sinking to Amazon S3, and when using the Taps within a Cascade.
There was also a massive speedup when sourcing from hundreds/thousands/millions of partitions.
The CHANGES.txt file has more details.
As always, the WIP page has all our latests builds.
And every build is in our maven repo:
Also a big thanks to the team at Homeaway for sponsoring the PartitionTap fixes and improvements.
