Subject Re: [VOTE] Release Apache Hadoop 2.7.0 RC0

- 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.
