Weird Behaviour on Solr 5x (SolrCloud)
Hi all,
after Mark Miller made it clear to me that 5x is supporting cloud with
ramdir, I have started playing with it and it seemed working smoothly,
except a weird behaviour.. here is the story of it:
Basically, I have pulled the code and built solr 5x, and the replace the war
file in webapps dir of my current installation... then i have started my
zookeeper servers..
after that i have started solr instances with the params below:
java -Djetty.port=7574 -DzkHost=zkserver2:2182 -jar start.jar (running on a
remote machine)
java -Dbootstrap_conf=true -DzkHost=zkserver1:2181 -jar start.jar (running
on local)
after both of them are up, i have indexed some docs, and both of the solr
instances were updated succesfully. after this point, i have killed one of
the solr (running on remote, not leader) and then restarted it again. there
was no errors in the log and everything seemed normal in the logs...
however, when i have checked the web interface for the one i have restarted
it showed 0 docs.. after that I ran q=*:* few times...
and thats the point which surprises me... randomly it returned 0 results and
then it returned correct numbers.. each time i make the same query, i get an
empty result set randomly... I have no idea why this is happening
here is the logs
for the one running on remote (which was restarted)

sure...
but before that could it be because of using RAM dir? because basically when
you restart solr the ram is gone and it tries to checks the old folder that
it had used... and as it cant find anything in the ram it shows an empty
index... could it be the reason? though still this not explains why after
restart it was not filled with the data from cloud...

I'm not sure - I guess I'll have to look into it - could you file a
JIRA issue with these details?

well... i find a way to avoid this... i dont know if it is the correct way or
i am simply bypassing the problem instead of fixing it..
when i delete the data/ folders contents before restarting, it can get the
index information from cloud without any problem...
so it is the way how solrcloud works? or i am missing something important
here?

is this because of zookeeper's load balancer or something like that? because
the results are returning totally randomly...
