----------------------------------------
Summary: webUI "descriptors" overwritten in Mini MR Cluster
Key: MAPREDUCE-6037
URL: https://issues.apache.org/jira/browse/MAPREDUCE-6037
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: mrv2
Affects Versions: 2.3.0
Reporter: Gera Shegalov
Unlike in Hadoop1, Hadoop2 does not use web.xml for webUI. However, the
programmatically set Guice descriptors overwrite each other, such that the last
component to start ends up owning all web ports (typically NM). This is a
regression from Hadoop1.
