Lei (Eddy) Xu created HDFS-10541:
------------------------------------
Summary: When no actions in plan, error message says "Plan was
generated more than 24 hours ago"
Key: HDFS-10541
URL: https://issues.apache.org/jira/browse/HDFS-10541
Project: Hadoop HDFS
Issue Type: Sub-task
Affects Versions: HDFS-1312
Reporter: Lei (Eddy) Xu
Priority: Minor
The message is misleading. Instead, it should make it clear that there are no
steps (or no action) to take in this plan - and should probably not error out.
{code}
16/06/16 14:56:53 INFO command.Command: Executing "execute plan" command
Plan was generated more than 24 hours ago.

This happens when a plan looks like the following one:
{code}
{"volumeSetPlans":[],"nodeName":"a.b.c","nodeUUID":null,"port":20001,"timeStamp":0}
