Subject [jira] [Commented] (SOLR-10147) Admin UI -> Cloud -> Graph: Impossible to see shard state
Date Mon, 20 Feb 2017 16:58:44 GMT

    [ https://issues.apache.org/jira/browse/SOLR-10147?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15874807#comment-15874807

Jan Høydahl commented on SOLR-10147:
------------------------------------

i like it, but will let [~upayavira] and others who can speak for consistency in colors etc
have a say. 
In your patch you set replica states to "Inactive" unless the node is "gone". Will a replica
for an inactive shard never be "Recovering" or "Down"?

> Currently in the Cloud -> Graph view there is a legend with color codes, but that
is for replicas only.
> We need a way to quickly see the state of the shard, in particular if it is active or
inactive. For testing, create a collection, then call SPLITSHARD on shard1, and you'll end
up with shards {{shard1}}, {{shard1_0}} and {{shard1_1}}. It is not possible to see which
one is active or inactive.
> Also, the replicas belonging to the inactive shard are still marked with green "Active",
while in reality they are "Inactive".
> The simplest would be to add a new state "Inactive" with color e.g. blue, which would
be used on both shard and replica level. But since an inactive replica could also be "Gone"
or "Down", there should be some way to indicate both at the same time...
