Please find the below error,

    *************************************************************************************
Found index level settings on node level configuration.

Since elasticsearch 5.x index level settings can NOT be set on the nodes 
configuration like the elasticsearch.yaml, in system properties or command line 
arguments.In order to upgrade all indices the settings must be updated via the 
/${index}/_settings API. Unless all settings are dynamic all indices must be closed 
in order to apply the upgradeIndices created in the future should use index templates 
to set default values. 

Please ensure all required values are updated on all indices by executing: 

curl -XPUT 'http://localhost:9200/_all/_settings?preserve_existing=true' -d '{
  "index.number_of_shards" : "2"
}'
