SolrCloud(5x) - Errors while recovering

Here is briefly what is happening:

I have a simple SolrCloud environment for test purposes, running with a
zookeeper ensemble, not the ones embedded in Solr.

I have 3 instances in the cloud, all of them are using RAMDirectory (which
is enabled by new Solr release to use with cloud)

After running zookeepers and connecting my solrs to them, the cloud is up
without any errors or problems. Then I have started indexing (which is much
slower than a single instance, i will open a topic about it too) and
everything is okay once again, all of the nodes get the sync'ed data from
the leader node. 

After that I have killed one Solr instance. then I have restarted it and in
the logs it keeps showing me these errors:

Re: SolrCloud(5x) - Errors while recovering

Posted by Mark Miller <ma...@gmail.com>.

Someone else has been seeing this on 5x as well - their must be a bug in the new file handling code (which is why it's still baking in 5x and not on 4x yet). I tried to trigger it in tests a while back, but had no look in the brief time I had. I'll try some manual tests when I get chance, as well as a little code review. Something is off.

RE: SolrCloud(5x) - Errors while recovering

Posted by deniz <de...@gmail.com>.

i have that issue with some larger size of indexes only... 12 - 14K docs are
working totally okay even after a node dies and then starts again but if
index is bigger, somehow i keep getting the lines above

It only seems to happen if a node dies while indexing.

RE: SolrCloud(5x) - Errors while recovering

Posted by deniz <de...@gmail.com>.

another update

having 300K docs causes the same error...

I think there is something going on with the size of the index stored...
after some point replication fails... 

any ideas how to bypass this?

thank you for the heads up 


and a surprising thing about my error.. when i use smaller size of
documents, i do not get any errors at all... I dont know why but I have just
tried to index only 12K docs, with few fields, with the same configuration,
and after a solr node is restarted, there is no errors at all and i got the
sync'ed index with the cloud for that node... 

there is nobody using solrcloud on their prod envs or with too large
datasets? or they are using one that they have customized for their own
needs?
