A number of issues have been identified with RC0. The following JIRAs need fixing before the next release candidate can be built:
HDFS-1288 - start-all.sh / stop-all.sh does not seem to work with HDFS MAPREDUCE-1920 - Job.getCounters() returns null when using a cluster MAPREDUCE-1926 - MapReduce distribution is missing build-utils.xml In addition, the following JIRAs need fixing before the release is finalized: HDFS-1292 - Allow artifacts to be published to the staging Apache Nexus Maven Repository MAPREDUCE-1929 - Allow artifacts to be published to the staging Apache Nexus Maven Repository Tom On Thu, Jul 8, 2010 at 7:55 PM, Aaron Kimball <aa...@cloudera.com> wrote: > I downloaded the "combined" tarball of 0.21.0-rc0 and set it up as a > pseudo-distributed Hadoop cluster. > > Everything seems to work; basic smoke tests pass.
