+1 (binding) - Downloaded source tarball and verified signature and checksum. - Built from source, including native code on Linux and Windows. - Ran a 3-node unsecured cluster. - Tested various HDFS and YARN commands, including sample MapReduce jobs. - Confirmed that SecondaryNameNode can take a checkpoint. - HADOOP-9629: Tested integration with Azure storage as an alternative FileSystem. - HADOOP-11394/11395/11396: Built site docs and confirmed presence of these fixes in the documentation for Hadoop Compatible File Systems. - HDFS-7604: Confirmed presence of DataNode volume failure reporting in web UI and metrics. - HDFS-7879: Ran nm -g libhdfs.so and dumpbin /exports hdfs.dll to confirm export of public API symbols in libhdfs.
Allen mentioned HDFS-8132, which reported a problem using JCarder on the build. Brahma, Todd and I have determined that root cause is incompatibility of the JCarder build with Java 7 classes. (2.7.0 is our first release compiling as Java 7.) This is not a problem that needs to hold up the release. Vinod, thank you for putting together the release.
