[VOTE] Release Hadoop 0.21.0 (candidate 2)
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.
*** This release candidate has not been tested extensively, so it
should not be considered stable.
*** Please download, test and vote before the vote closes on Thursday 19 August.
http://people.apache.org/~tomwhite/hadoop-0.21.0-candidate-2/
The hadoop-0.21.0.tar.gz file is an old-style combined release which
includes Common, HDFS, and MapReduce.
Thanks,
Tom

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.

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.
