Just wondering if anyone has seen this before and might understand why this is
happening
Environment:
Solr 5.3.1 in Solr Cloud (3 shards each with 3 replicas across 3 EC2 Vms)
100m documents (20+ GB index)
Previously we’ve done reloads of a collection after changing solrconfig.xml
without any issues.
This time we saw it across 3 of 3 environments where we got several Solr’s
showing “IndexWriter is closed” errors and had to stop and restart those Solr
instances.
In our final environment we skipped the RELOAD and just did solr stop, solr
start.
The solrconfig.xml change we made was turning on the replication handler (not
sure if this has any bearing on the issue)
<requestHandler name="/replication" class="solr.ReplicationHandler">
<lst name="defaults">
<str name="maxWriteMBPerSec">96</str>
<str name="httpConnTimeout">60000</str>
<str name="httpReadTimeout">60000</str>
</lst>
</requestHandler>
Is there anything “unsafe” about reload on a collection that is handling live
traffic in that version?
Cheers!
