On behalf of the Apache Hadoop Project Management Committee, I am pleased to announce the release of Apache Hadoop 3.3.6.
It contains 117 bug fixes, improvements and enhancements since 3.3.5. Users of Apache Hadoop 3.3.5 and earlier should upgrade to this release. https://hadoop.apache.org/release/3.3.6.html Feature highlights: SBOM artifacts ---------------------------------------- Starting from this release, Hadoop publishes Software Bill of Materials (SBOM) using CycloneDX Maven plugin. For more information about SBOM, please go to [SBOM](https://cwiki.apache.org/confluence/display/COMDEV/SBOM). HDFS RBF: RDBMS based token storage support ---------------------------------------- HDFS Router-Router Based Federation now supports storing delegation tokens on MySQL, [HADOOP-18535](https://issues.apache.org/jira/browse/HADOOP-18535) which improves token operation through over the original Zookeeper-based implementation. New File System APIs ---------------------------------------- [HADOOP-18671](https://issues.apache.org/jira/browse/HADOOP-18671) moved a number of HDFS-specific APIs to Hadoop Common to make it possible for certain applications that depend on HDFS semantics to run on other Hadoop compatible file systems. In particular, recoverLease() and isFileClosed() are exposed through LeaseRecoverable interface. While setSafeMode() is exposed through SafeMode interface. Many thanks to everyone who helped in this release by supplying patches, reviewing them, helping get this release building and testing and reviewing the final artifacts. Weichiu
