I have created a new candidate build for Hadoop 0.21.0. This fixes
MAPREDUCE-1920 and MAPREDUCE-1926 which were found for the previous
release candidate (0).

This release is being classified as a minor release, which means that
it is API compatible with 0.20.2.

The hadoop-0.21.0.tar.gz file is an old-style combined release which
includes Common, HDFS, and MapReduce.

Thanks,
Tom

After MAPREDUCE-1920, some contrib tests are timing out. Created MAPREDUCE-2012 for the same.

Thanks

Thanks for finding and fixing MAPREDUCE-2012, Amareshwari. I'll roll a
new release candidate with it in. RC1 also has a potential security
hole in the Linux task
controller, which also means we need a new release candidate.

Cheers,
Tom

I have created a new candidate build for Hadoop 0.21.0. This fixes
MAPREDUCE-2012 and MAPREDUCE-2014 which were found for the previous
release candidate (1).

This release is being classified as a minor release, which means that
it is API compatible with 0.20.2.

should not be considered stable.

The hadoop-0.21.0.tar.gz file is an old-style combined release which
includes Common, HDFS, and MapReduce.

Thanks,
Tom

+1 Based on running a job in pseudo-distributed mode, and checking the
signature and checksum.

I verified the checksum & signature and ran some of the example
programs.  I also ran RAT to check that sources are licensed correctly.

I only examined the merged artifact.  Do we need to release the others?

The out-of-box experience isn't great.  There's no documentation at the
top-level telling how to get started.  In a subsequent release we might
add links to the various documents.

Also, 'bin/start-all.sh' warns that one should use start-dfs.sh and
start-mapred.sh instead, but those scripts, out-of-the-box, complain
that that they can't find Common.

There are some empty java source files in the release, namely:

./common/src/java/org/apache/hadoop/fs/ftp/FTPFileSystemConfigKeys.java

./hdfs/src/java/org/apache/hadoop/hdfs/server/namenode/metrics/NameNodeStatisticsMBean.java
./hdfs/src/java/org/apache/hadoop/hdfs/server/namenode/metrics/NameNodeStatistics.java
./hdfs/src/java/org/apache/hadoop/hdfs/server/datanode/metrics/DataNodeStatistics.java
./hdfs/src/java/org/apache/hadoop/hdfs/server/datanode/metrics/DataNodeStatisticsMBean.java

These issues should not prevent this release, in my opinion.

I think we can release just the merged artifact. It contains the
source code for the three subprojects, and you can build separate
binaries from it, if needed.

I think this is because HADOOP_HOME was not set. We can improve this
to default HADOOP_HOME if not set; I'll create a JIRA.

I've created HADOOP-6917 and HDFS-1349 to tackle these.

With three binding PMC +1 votes, the vote passes. I'll start work to
push out the release.
