> PROBLEM: Not obvious when the namenode is in safemode. It does show safemode
> status in small text but it would be nice if there was a color indicator in
> Ambari for HDFS showing it is in safemode
> BUSINESS IMPACT: Can decrease confusion when safemode is on either due to
> manually placing it in safemode, a restart, or low HDFS space that
> automatically placed it in safemode
> USE CASE: Customer did not realize safemode had been entered due to low HDFS
> space and it took a while to figure out status
> SOLUTION:
> - Plan: (see attached)
> If NN is in safe mode, make the text 'in safe mode' orange.
> If NN is not in safe mode, the text remains in grey color.
> - A similar scenario we did:
> For HDFS Upgrade Status, if 'No pending upgrade', the text remains in grey
> color;
> If upgrade required, the text would be orange.
