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.

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