Hi, I am trying to implement some scripting to detect if all Zookeepers have started in a cluster, then restart the solr servers. Has anyone achieved this yet through scripting?
I also saw there is the ZookeeperClient that is available in .NET via a nuget package. Not sure if this could be also implemented to check if a zookeeper is running. Any thoughts?

I noticed that the Solr service was restarted indefinetly when running it as a background service. its also needed to stop the windows service. This test worked well here (on Windows 2012): REM Test for running solr 5.3.1 as a windows service C:\nssm\nssm64.exe install "Solr 5.3.1" C:\search\solr-5.3.1\bin\solr.cmd "start -f -p 8983" On 8 October 2015 at 04:34, Zheng Lin Edwin Yeo <edwinye...@gmail.com> wrote: > Hi Adrian and Upayavira, > > It works fine when I start Solr outside NSSM. > As for the NSSM, so far I haven't tried the automatic startup yet.
