Andrew Wang commented on HADOOP-13688:
--------------------------------------
The other issue I noticed is that there seems to be tons of extra content in
the javadoc jars, like other jars and classfiles. It looks like it's sucking
down the entire target directory:
After unzipping the hadoop-common javadoc jar:
{noformat}
-> % ls
allclasses-frame.html findbugsXml.xml
hadoop-maven-plugins-protoc-checksums.json META-INF src-html
allclasses-noframe.html generated-sources
help-doc.html org
stylesheet.css
antrun generated-test-sources
index-all.html overview-frame.html test
archive-tmp hadoop-annotations.jar
index.html overview-summary.html test-classes
classes hadoop-common-3.0.0-alpha2-SNAPSHOT
javadoc-bundle-options overview-tree.html test-dir
constant-values.html hadoop-common-3.0.0-alpha2-SNAPSHOT.jar
jdiff.jar package-list xerces.jar
deprecated-list.html hadoop-common-3.0.0-alpha2-SNAPSHOT-sources.jar
log script.js
docs-src hadoop-common-3.0.0-alpha2-SNAPSHOT-tests.jar
maven-archiver serialized-form.html
findbugsExcludeFile.xml hadoop-common-3.0.0-alpha2-SNAPSHOT-test-sources.jar
maven-shared-archive-resources site

-> % find . -name "*.class" | wc -l

andrew@zanarkand [03:21:11 PM] [/tmp/javadoc]
-> % find . -name "*.jar" | wc -l
85
-> % find . -name "*.jar" -exec wc -c {} \; | awk -e '{SUM+=$1} END {print
SUM}'

{noformat}
Since the jarfiles by themselves are another 41MB, there's the potential to
really streamline the javadoc jars.

> We generate source code with line numbers for inclusion in the javadoc JARs.
> Given that there's github and other online viewers, this doesn't seem so
> useful these days.
> Disabling the "linkSource" option saves us 40MB for the hadoop-common javadoc
