+0 (non-binding) - Downloaded source - Built from source - Ran a pseudo-distributed cluster - Read documents downloaded from binary tarball - Looked Web UIs
I found several issues to be fixed. - HDFS-8149: The footer of Web UI "Hadoop, 2014" is old I'm thinking this is a regression from Hadoop 2.6.0. - HADOOP-11835: "hadoop version" outputs "Subversion Unknown -r Unknown" (Also, there are some "Unknown" version in Web UI) - HADOOP-11836: The content of index.html should be updated for 2.7.0. I'm thinking this two issues are not blocker. Regards, Akira On 4/15/15 11:05, Chris Nauroth wrote:

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.

Disclaimer, please note a JDK difference, 2.6.0 ran with jdk1.7 while 2.7.0 had jdk1.8, so some of the improvement may be from Java 1.8.0, that said, the 2.7.0 benchmarks compare well against current 2.6.0.
