Subject [jira] [Commented] (AIRAVATA-2625) Derive and present Text outputs in Experiment summary
Date Wed, 24 Jan 2018 19:13:00 GMT


Dimuthu Upeksha commented on AIRAVATA-2625:

This is might require few changes to output data staging task and there are few restrictions.
Because we need to read the file to extract the values, we need to read the file content to
the JVM heap. Risk of that is, if we read a large file (several gigs) into the heap, it will
cause OOM error and eventually the whole JVM might crash. So we have to come up with a reasonable
size cap for the files that are scanned (2 - 5 MB?) and if the file is larger than that, we
simply ignore the file and notify the user that output file is too big to scan.

>          Issue Type: Bug
>          Components: Airavata System
>    Affects Versions: 0.18
>            Reporter: Eroma
>            Assignee: Suresh Marru
>            Priority: Major
> Currently the available application outputs are in the form of stdout, stderr and URI
(files). Going forward to have text (String, Integer, Float) outputs directly in the experiment
> These text outputs to be displayed as key+value pairs and when defining should be defined
a file to derive from, e.g. stdout
> At a given time from a single file one or many of these key+value pairs could be derived.
Also gateway admin can define multiple files to derive multiple of these values.
> These would be displayed to user in experiment summary and in detailed experiment summary
in admin dashboard experiment statistics.
> These should also be displayed to any other gateway user it is shared with.
