----------------------------------------------------------------
CoordActionInputCheckXCommand check hdfs papth every 90 sec and if we use
"oozie.service.ELService.latest-el.use-current-time" and it's calculate path
with relative to current time.
We need to do same behavior while checking path.
We are not going to show any random path.
{{coord:latest(int n)}} is a very simple usecase and showing it as
{{coord:latest(0)[\/data/metadata\/A\/\${YEAR}\/\${MONTH}\/\${DAY}\/\${HOUR}]}}
might help for some user.
But i am very sure that some user will still get confused as available data
might be month old.
For usecase like {{coord:latest(-2000,0)}}, i don't think showing like
{{coord:latest(-2000,0)[/data/metadata/A/\${YEAR}/\${MONTH}/\${DAY}/\${HOUR}]}}
will help user anyway.
He wanted to know which dataset from -2000,0 is missing and I have seen lot of
users struggling with that.
We need to compute path based on frequency, current time, start time etc.. and
show them actual path, rather showing them uri-template and expecting them to
compute path. I guess user is expecting to see actual missing path rather than
uri-template .

> Project: Oozie
> Issue Type: Bug
> Reporter: Jaydeep Vishwakarma
> Assignee: Jaydeep Vishwakarma
>
> User used to face difficulty when coord instance wait for coord:latest( n ).
> As oozie -info does not show which path it is waiting for. At the user end
> has to see the coord definition. If we show uri-template it will improve
> debuggability.
