Debadatta updated HDDS-8465:
----------------------------
Description:
Currently on the SCM Web UI we have a node-status table that provides
information about the status of the DataNodes Hostname,Operational State &
Commisioned state.
In this JIRA I would like to propose to apply data rendering in nodestatus
table. we need to enable sorting symbol in the way column is selected. Lets say
sorting happens on ascending order only that particular column is selected
other column selection will not be enabled and for ascending sorting asc
symbol should be highlighted .

Currently on the SCM Web UI we have a table that provides information about the
status of the DataNodes in a way that is summarizes the number of nodes in
different states, and represent the results in a table.
In this JIRA I would like to propose to remove this table, and introduce a new
approach to show the information, and open the possibility to add new things
easily.
If we show the DataNode host name in the first column, then we have the
possibility to provide information on a per DataNode basis, similarly as we
have in the HDFS NameNode UI. With the possibility to filter and sort the table
contents, and proper pagination, the table can provide any kind of easily
accessible DN information that SCM is aware of.
Changing the table to this format, allows us to link from the SCM UI to the DN
UI, it allows us to provide various other information about the DataNodes, and
also it contain more useful information about which node is in which state
instead of showing just an aggregate. The links come in handy for example for
integrating the DN WebUIs as well with Knox, after KNOX-2833. I know Recon can
provide the same, and already has a similar table, but all in all Recon is an
optional component, so we should provide at least a subset of the information
shown in Recon on other UIs.
The initial aim covered in this JIRA is to show the DN hostname as a link to
the DN WebUI in the first column of the new table, then show the health and
decommissioning state of the DN in the 2nd and 3rd columns leaving the same
information available. It is out of scope to add new things, those might come
later on.
