-----------------------------
Summary: Display readable last contact time for dead nodes on NN
webUI
Key: HDFS-6722
URL: https://issues.apache.org/jira/browse/HDFS-6722
Project: Hadoop HDFS
Issue Type: Improvement
Reporter: Ming Ma
For dead node info on NN webUI, admins want to know when the nodes became dead,
to troubleshoot missing block, etc. Currently the webUI displays the last
contact as "the unit of seconds since the last contact". It will be useful to
display the info in Date format.
