Hi, I am working on a test setup with Solr 6.1.0 cloud with 1 collection sharded across 2 shards with no replication. When triggered a SPLITSHARD command it throws "java.lang.OutOfMemoryError: Java heap space" everytime. I tried this with multiple heap settings of 8, 12 & 20G but every time it does create 2 sub-shards but then fails eventually. I know the issue => https://jira.apache.org/jira/browse/SOLR-5214 has been resolved but the trace looked very similar to this one. Also just to ensure that I do not run into exceptions due to merge as reported in this ticket, I also tried running optimize before proceeding with splitting the shard. I issued the following commands :
1. http://localhost:8983/solr/admin/collections?collection=testcollection&shard=shard1&action=SPLITSHARD This threw java.lang.OutOfMemoryError: Java heap space 2. http://localhost:8983/solr/admin/collections?collection=testcollection&shard=shard1&action=SPLITSHARD&async=1000 Then I ran with async=1000 and checked the status. Every time It's creating the sub shards, but not splitting the index. Is there something that I am not doing correctly? Please guide. Thanks, Atita
