ES 5.3 on AWS cloud. _reindex got stopped after some docs

Hi,
I am running the following command from Kibana. I use ES 5.3 on AWS ES. My reindexing got stopped after around 80K documents. Why? How to troubleshoot this? I tried two times with different index name. It stopped at the same place.
POST _reindex
{
"source": {
"index": "twitter"
},
"dest": {
"index": "new_twitter"
}
}

thanks

Anything in logs?
What gives

GET _cat/indices?v

BTW did you look at https://www.elastic.co/cloud and https://aws.amazon.com/marketplace/pp/B01N6YCISK ?

Cloud by elastic is one way to have access to all features, all managed by us. Think about what is there yet like Security, Monitoring, Reporting, SQL and what is coming like Canvas...

Hi David,
Here is the output of _cat/indices?v:

I am trying to copy from aem6_v6 to aem6_v8.

thanks

Are you using nested documents? What is the output of (please for small content just copy, paste and use the format button):

GET aem6_v6/_mapping
GET aem6_v6/_search?size=0

Hi David,
Yes, I have a nested. https://screencast.com/t/5W64MwS6

And

thanks

Please don't use Screencast for that. Just use markdown style like:

```
CODE
```

What gives:

GET aem6_v8/_search?size=0

What are the logs saying?
What is the output of the reindex API call?

  1. Output of aem6_v8/_search?size=0:
    {
    "took": 63,
    "timed_out": false,
    "_shards": {
    "total": 1,
    "successful": 1,
    "failed": 0
    },
    "hits": {
    "total": 88999,
    "max_score": 0,
    "hits": []
    }
    }
  1. reindex API call output:
    Request failed to get to the server (status code: 504)
  2. Logs? Where can I find the logs? In Cloudwatch?

thanks

Logs? I don't know. May be ask AWS support.

FWIW with elastic cloud you could get the logs from the console and more than that ask the support team about your problem.
