doomleika created HADOOP-10396:
----------------------------------
Summary: The 2.X official document is in sorry state.
Key: HADOOP-10396
URL: https://issues.apache.org/jira/browse/HADOOP-10396
Project: Hadoop Common
Issue Type: Bug
Components: documentation
Affects Versions: 2.2.0
Reporter: doomleika
Priority: Minor
Hello, I am new to Hadoop 2.X line and I found most of the document does
poorly, hard to read, and misleading to a point it's doing more harm than good.
Example, most documents in http://hadoop.apache.org/docs/r2.2.0/ identify
itself as 'Apache Hadoop 2.1.1-beta' instead of 'Apache Hadoop 2.2 release'
The first section building hadoop from source tells nothing about what package
required to be built (jdk?g++?)
That's just tip of iceberg, that second page 'single cluster setup', that
second section 'Mapreduce Tarball' says:
'You should be able to obtain the MapReduce tarball from the release. If not,
you should be able to create a tarball from the source.'
What it should do it put a like to hadoop download release link. let alone all
that confusing test in section 3 'Setting up the environment' which did no
explaination on what does all that do.
Lots of documents in release are ridden problems like this. Review is needed
for those document or at least a warning about it may be outdated.
