+1 (binding) -Tried a dry-run merge of HADOOP-12930 to trunk. -Successfully built distro on Windows. -Ran "hdfs namenode", "hdfs datanode", and various interactive hdfs commands through Cygwin. -Reviewed documentation.
Allen, thank you for the contribution. Would you please attach a full patch to HADOOP-12930 to check pre-commit results? While testing this, I discovered a bug in the distro build for Windows. Could someone please code review my patch on HADOOP-13149? --Chris Nauroth On 5/9/16, 1:26 PM, "Allen Wittenauer" <a...@apache.org> wrote: > > Hey gang! > > I¹d like to call a vote to run for 7 days (ending May 16 at 13:30 PT) to >merge the HADOOP-12930 feature branch into trunk.
