2017-12-01 Haven't written one of these in a month. I had high hopes for RC0, but it failed due to HADOOP-15058 <https://issues.apache.org/jira/browse/HADOOP-15058?src=confmacro> - create-release site build outputs dummy shaded jars due to skipShade PATCH AVAILABLE which Sangjin found, and then a number of other blockers were found shortly after that. We're back to blocker burndown. My new (realistic) goal is to get 3.0.0 out before Christmas. We could always use more help with reviews; most things are patch available. Highlights: Red flags: Previously tracked blockers that have been resolved or dropped: GA blockers: - HDFS-12840 <https://issues.apache.org/jira/browse/HDFS-12840?src=confmacro> - Creating a replicated file in a EC zone does not correctly serialized in EditLogs PATCH AVAILABLE : Has gone through several rounds of review, looks close. - HADOOP-15080 <https://issues.apache.org/jira/browse/HADOOP-15080?src=confmacro> - Cat-X transitive dependency on org.json library via json-lib OPEN : New issue, waiting on LEGAL but we might need to pull this entire feature. - HADOOP-15059 <https://issues.apache.org/jira/browse/HADOOP-15059?src=confmacro> - 3.0 deployment cannot work with old version MR tar ball which break rolling upgrade PATCH AVAILABLE : Has gone through some review and has a +1 from Daryn, could use confirmation from Vinod and others - HADOOP-15058 <https://issues.apache.org/jira/browse/HADOOP-15058?src=confmacro> - create-release site build outputs dummy shaded jars due to skipShade PATCH AVAILABLE : Needs review, asked Allen but might need someone else to help. GA criticals: - HDFS-12872 <https://issues.apache.org/jira/browse/HDFS-12872?src=confmacro> - EC Checksum broken when BlockAccessToken is enabled PATCH AVAILABLE : Patch needs review - YARN-7381 <https://issues.apache.org/jira/browse/YARN-7381?src=confmacro> - Enable the configuration: yarn.nodemanager.log-container-debug-info.enabled PATCH AVAILABLE : Has gone through some review and Wangda +1'd, could use confirmation from Ray and others Features merged for GA: - Erasure coding - Testing is still ongoing at Cloudera, which resulted in HDFS-12840 <https://issues.apache.org/jira/browse/HDFS-12840?src=confmacro> - Creating a replicated file in a EC zone does not correctly serialized in EditLogs PATCH AVAILABLE and HDFS-12872 <https://issues.apache.org/jira/browse/HDFS-12872?src=confmacro> - EC Checksum broken when BlockAccessToken is enabled PATCH AVAILABLE . - Classpath isolation (HADOOP-11656) - No change. - Compat guide (HADOOP-13714 <https://issues.apache.org/jira/browse/HADOOP-13714>) - We slid a couple more changes into 3.0.0 after RC0 was cancelled, making this work more complete. - TSv2 alpha 2 - No change. - API-based scheduler configuration YARN-5734 <https://issues.apache.org/jira/browse/YARN-5734?src=confmacro> - OrgQueue for easy CapacityScheduler queue configuration management RESOLVED - No change. - HDFS router-based configuration HDFS-10467 <https://issues.apache.org/jira/browse/HDFS-10467?src=confmacro> - Router-based HDFS federation RESOLVED - No change. - Resource types YARN-3926 <https://issues.apache.org/jira/browse/YARN-3926?src=confmacro> - Extend the YARN resource model for easier resource-type management and profiles RESOLVED - Had some post-merge issues that were resolved, nothing outstanding.
