Subject [jira] Updated: (HADOOP-6461) webapps aren't located correctly post-split
Date Sun, 24 Jan 2010 19:30:17 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-6461?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Steve Loughran updated HADOOP-6461:

    Fix Version/s: 0.22.0
           Status: Patch Available  (was: Open)

This patch is against head
# throws FileNotFoundException if the file is not there. This makes it easy to distinguish
failure from missing file from other failures
# Has a test that this fails if passed in a nonexistent webapp
# Contains a refactoring of the HttpServer functional tests with a shared base class and a
move of all the tests to JUnit4 test cases. This means that test webapps are now created in
one class, for easier maintenance.

> 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.
