Folks,
Somewhere between MR-279 and mavenization we have broken the support for
allowing _developers_ to run single-node installs from the non-packaged 'build'
i.e. ability to run single-node clusters without the need to use a tarball/rpm
etc. (I fully suspect MR-279 is blame as much as
Arun,
There are instructions on how to run 0.23/trunk from the dev tree here:
http://wiki.apache.org/hadoop/HowToSetupYourDevelopmentEnvironment#Run_HDFS_in_pseudo-distributed_mode_from_the_dev_tree
I think also at issue is the maven build system. I don't know if its
intended, but if I change a single .java file, mvn -Pdist -P-cbuild
-Dmaven.javadoc.skip -DskipTests install runs a TON of stuff It takes
a 1m 29s to finish even if there are NO changes anywhere. I doubt this is
how it should
Single node developer build may be supported independently from
package installed builds. There are multiple ways to achieve this.
The current method is using shell script to support different
deployment conditions. This is a awkward and inefficient way to
maintain compatibility to support
