Elastic Stack Elasticsearch
1

Hi, i get this stack while using _reindex API to do a simple rename operation using java low level client on elastic 6.2.3 OSS in a docker container :

GET _reindex/?wait_for_completion=false
{
  "source": {
    "index": "foo-1"
  },
  "dest": {
    "index": "bar-1"
  }
}

the stack trace is

Please wrap snippets in ``` or discuss will eat the formatting.

These:

 Caused by: org.elasticsearch.transport.RemoteTransportException: [VkMcoUb][172.22.0.2:9300][indices:data/read/search[phase/query/scroll]]
 Caused by: org.elasticsearch.search.SearchContextMissingException: No search context found for id [625]

Make it look like one of the nodes that was servicing the scroll went down. When that happens the _reindex can't recover its process so it dies.
