Many users are requesting most necessary features, so that’s why we release so fast.
Many of this featuress a necessary to run YARN cluster, such as RM fail-over/ HA, etc
2.6/2.7/2.8 are versions which most prod cluster are using, so many feature development remains in the background and many community effort are focusing on stablizing features.
Again, the most essential YARN doesn’t meet user’s requirement anymore, that’s why we released 3 minor releases in 6 months, and include features like:
YARN Federation (larger cluster)
GPU / FPGA, etc.
Even though TF provide options to use GPU memory less than whole device provided. But we cannot enforce this from external.
High level talk on ATSv2, it is scalable solution compared to 1.5.
