Seamless access to the Java SE API documentation
API documentation for Java SE and Hadoop (and other frameworks) can be downloaded for offline access. But, the Hadoop API documentation is not aware of the offline copy of Java SE documentation. For seamless interaction between the two API, reference to http://java.sun.com/....../ConcurrentLinkedQueue.html in the Hadoop API should be replaced with file:///home/praveensripati/....../ConcurrentLinkedQueue.html The below command will replace all such references in the API documentation (note that back slash has to be escaped) find ./ -type f -name *.html -exec sed -i 's/http:\/\/java.sun.com\/javase\/6\/docs\//file:\/\/\/home\/praveensripati\/Documents\/Java6API\//' {} \; This enables for seamless offline access and better productivity.
