Long time since the previous update. In the meanwhile, we released alpha4! Onward to beta1.

Red flags:

Beta1 is targeted for 09/15, and there are a number of blockers we kicked down the road that need to be resolved.

Miscellaneous blockers

HADOOP-14284 (Shade Guava everywhere): Progressing, though trying to resolve Curator issues
HADOOP-13363 (Upgrade to protobuf 3): Waiting on the Guava shading first
HADOOP-14330 (Kerby breaks multiple SPN support): uncovered from secure testing with Oozie, unknown if other Kerby bugs are lurking
YARN-5894 (fst licensing): no assignee yet

beta1 features:

Erasure coding
- Need to wrap up pluggable EC work and other must-dos, reasonable confidence since these are actively being worked on
Addressing incompatible changes
- YARN-6142 (compatibility with 2.x): Still need automated testing for this
- HDFS-11096 (compatibility with 2.x): Sean has revived efforts here and has a rolling upgrade script under review, closing on some incompats we found too.
Classpath isolation (HADOOP-11656)
- The subtasks were not completed for alpha4. Sean has revived efforts and is committed to finishing this for beta1.
Compat guide (HADOOP-13714)
- Daniel posted an initial patch for discussion, but stalled out

Red flags:

Less than a month out and some new blockers just surfaced, need to keep pushing.
