Todd Lipcon updated HADOOP-6461:
--------------------------------
Attachment: hadoop-6461.txt
Patch change getWebAppsPath to look specifically for webapps/<appname>.
I tested this from within my build trees (pointed my hdfs checkout as
HADOOP_HDFS_HOME). Before the patch, the NN web UI didn't load. With the patch,
it works correctly. Since this is a cross-component issue, not sure how to
correctly unit test it, but it's quite obvious to verify manually.
> webapps aren't located correctly post-split

> Post-split, when one builds common it creates an empty build/webapps dir. If
> you then try to launch the NN for example using
> HADOOP_HDFS_HOME=/path/to/hdfs hdfs namenode, HttpServer.getWebAppsPath
> locates the empty common webapps dir, and the NN web UI fails to load.
