--------------------------------------
Summary: UI freeze if Zookeeper is down
Key: SOLR-9539
URL: https://issues.apache.org/jira/browse/SOLR-9539
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Components: web gui
Affects Versions: 6.2
Reporter: Mikhail Khludnev
# Download Solr 6.2 and Zookeeper 3.4.6
# Launch Zookeeper {{$zkServer}}
# Launch two Solrs {{$bin\solr start -z localhost:2181 -e cloud}}
# stop Zookeeper
# get to new Admin UI. It's frozen. Respond with placeholders after few
minutes. However, solr urls respond well.
# launch Zookeeper back, UI respond smoothly and rapidly.
I briefly checked chrome debug, I saw that every ...js response is slow,
something like request filter might check zookeeper with timeout, but I don't
know.
