[jira] [Updated] (HBASE-13839) Fix AssgnmentManagerTmpl.jamon
issues (coloring, content etc.)
[ https://issues.apache.org/jira/browse/HBASE-13839?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Matt Warhaftig updated HBASE-13839:
-----------------------------------
Attachment: HBASE-13838_post.tiff
HBASE-13838_pre.tiff
Attached 'HBASE-13838_pre.tiff' and 'HBASE-13838_post.tiff' to show the 'Region In Transition' UI improvements (hopefully got all the enhancements in that single screenshot :-) ).
If you want to recreate, to have long lasting RITs add the following line and split 'TestTable':

> The template for the RIT in the Master status page, AssignmentManagerTmpl.jamon) has a few issues:
> - The oldest RIT should not be _red_, looks like a failed entry
> The RIT entries should be for example yellow/amber when over the threshold time, and red if 2x the threshold - or red for the oldest once over the threshold.
> - Region count over RIT threshold should only be colored if > 0
> The summary line (first of two) should not be colored unless there is a value > 0 in it.
> - Color is overriden by table-stripped CSS style!
> The Bootstrap stylesheet cancels out the hardcoded coloring! The table-stripped resets the conditional coloring and should be fixed. Best is to use "alert-warning" etc. that come from the Bootstrap theme stylesheet. That should maybe already work in combination with the "table-stripped" from the same.
> - Should sort descending by time
> Currently the list of regions is sorted by encoded region name. Better is to have the table sorted by RIT time descending.
> We should also think about a pagination option for the currently hardcoded 100 entries max. Maybe a separate issue?
