[jira] [Updated] (HDDS-2861) Support Freon progressbar in
non-interactive element
[ https://issues.apache.org/jira/browse/HDDS-2861?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Marton Elek updated HDDS-2861:
------------------------------
Description:
Freon tests use the ProgressBar to show the current progress of the Freon tests.
Progress bar use "\r" to print out a nice, interactive progressbar to the same line.
Unfortunately this doesn't work very well when the standard output is redirected to a file (or in a containerized environment). I would suggest to use a simplified method using log4j in non-interactive environments.
The easiest way to do is to use "System.console()" java method. If it returns with null we are in a non interactive environment. We can also increase the logging period from 1s to 10s in case of non-interactive environment (==long term testing).
