For all those of you who would want to help with testing Hadoop 0.22 release, I've setup a job on Bigtop to produce an entire Hadoop stack on top of 0.22.
The good news is that it is now super simple to give it all a spin. If you are on Ubuntu/Debian you can try: $ cd /etc/apt/sources.list.d $ sudo wget -O bigtop.list http://bigtop01.cloudera.org:8080/job/Bigtop-hadoop22-ubuntu-lucid/lastSuccessfulBuild/artifact/output/bigtop.list $ sudo apt-get update $ sudo apt-get install 'hadoop*' 'hbase*' and if you're on RedHat/CentOS: $ cd /etc/yum.repos.d/ $ sudo wget -O bigtop.repo http://bigtop01.cloudera.org:8080/job/Bigtop-hadoop22-centos5/lastSuccessfulBuild/artifact/output/bigtop.repo $ yum install 'hadoop*' 'hbase*' The bad news is that so far we only have HBase compiling against .22 and the Hadoop itself seems to be in need of some tweaks. E.g.: https://issues.apache.org/jira/browse/HDFS-2377 That said, after manually patching /usr/lib/hadoop/bin/hdfs and doing: # for i in /etc/init.d/hadoop-* ; do $i start ; done I now have Hadoop 0.22 and HBase 0.92 to play with! Thanks, Roman.
