branch-3.0.0-alpha2 has been created in git. Still on track for planned alpha2 release at the end of January.

Notable release blockers:

• YARN-5667 (Move HBase backend code in ATS v2 into its separate module): One subtask left at YARN-5928, looks close to commit.
• Also resolved blockers like HADOOP-13996, YARN-6071, YARN-5646, YARN-6072, HADOOP-13961, HDFS-11312, YARN-6068, HADOOP-13780 since last update. Wow!

Development activity

• Addressing incompatible changes
  • HDFS-11096 (compatibility with 2.x): Sean filed and fixed HDFS-11312, which was a PB incompatibility. Seems like this work is complete on the HDFS side, but we still need YARN and MR help.
• Erasure coding
  • Andrew went through and re-triaged all the JIRAs on HDFS-8031, using the "hdfs-ec-3.0-must-do" and "hdfs-ec-3.0-nice-to-have" labels. HDFS-8031 more closely reflects what we want to get done for 3.0, and the labels are now tracked on the JIRA dashboard.
• Classpath isolation (HADOOP-11565)
  • Arun added a Maven variable to skip shading for faster build times. No progress on subtasks required for beta1.
• Tomcat to Jetty conversions
  • HADOOP-13597 (KMS): this patch went in
  • HDFS-10860 (HttpFS): Patch up and gone through initial review
