Subject [jira] [Commented] (SOLR-5364) SolrCloud stops accepting updates
Date Sat, 19 Oct 2013 07:56:42 GMT


Chris commented on SOLR-5364:

Actually, I could be wrong with that last comment, was confused with another ticket. I'll
grab the latest snapshot and test it.

fwiw, as a desperate work around I wrote my own DIH processor, which too ran into this after
~1.4m docs were processed.

>                 Key: SOLR-5364
>                 URL:
>             Project: Solr
>          Issue Type: Bug
>          Components: SolrCloud
>    Affects Versions: 4.4, 4.5, 4.6
>            Reporter: Chris
>            Priority: Blocker
> I'm attempting to import data into a SolrCloud cluster. After a certain amount of time,
the cluster stops accepting updates.
> I have tried numerous suggestions in IRC from Elyorag and others without resolve.
> I have had this issue with 4.4, and understood there was a deadlock issue fixed in 4.5,
which hasn't resolved the issue, neither have the 4.6 snapshots.
> I've tried with Tomcat, various tomcat configuration changes to threading, and with Jetty.
Tried with various index merging configurations as I initially thought there was a deadlock
with concurrent merg scheduler, however same issue with SerialMergeScheduler.
> The cluster stops accepting updates after some amount of time, this seems to vary and
is inconsistent. Sometimes I manage to index 400k docs, other times ~1million . Querying 
the cluster continues to work. I can reproduce the issue consistently, and is currently blocking
our transition to Solr.
> I can provide stack traces, thread dumps, jstack dumps as required.
> Here are two jstacks thus far:
> I have got these jstacks from the latest 4.6 snapshot, also running solrj snapshot. The
issue is also consistently reproducable with BinaryRequest writer.
