Thanks a lot Anshum for your quick reply. I checked the clusterstate.json and there it says the two new shards as under construction.
It shows : shard1 : active shard2 : active shard1_1 : construction shard1_0 : construction But the loggers don't indicate any other progress in that. Also when I try to delete the newly created shards, it is not able to delete ( which I think should be the case as it is still under construction) Is there any workaround to resolve this for now? like some reqestParam specifying a higher timeout value? -- View this message in context: http://lucene.472066.n3.nabble.com/SPLITSHARD-failed-to-invoke-SPLIT-core-admin-command-tp4109431p4109441.html Sent from the Solr - User mailing list archive at Nabble.com.
