Kihwal Lee created HADOOP-14607:
-----------------------------------
Summary: NPE while getting list of live nodes via jmx
Key: HADOOP-14607
URL: https://issues.apache.org/jira/browse/HADOOP-14607
Project: Hadoop Common
Issue Type: Bug
Affects Versions: 2.7.3
Reporter: Kihwal Lee
I saw this back in February during an upgrade. A namenode was restarted and
all nodes registered, but some didn't block reported. Clicking datanodes tab in
the web UI wasn't working, but other UI components were working. This got
resolved later on its own.
