Hi,
I am trying to reindex data from an Elasticsearch v6.8 cluster(basic license without ReadOnlyRest plugin) to a new v7.8.0 cluster(with ReadOnlyRest es 1.25.0_es7.8.0 and kibana enterprise 1.25.0_es7.8.0 installed).
When I initiate a remote reindex in Kibana like below, my new cluster(v7.8) creates the index-es6-log with a giant mapping. By giant mapping, I mean it has over 1000 fields and obviously, many of them are from other indices in the same v6.8 cluster.
POST _reindex?wait_for_completion=false
{
"source": {
"remote": {
"host": "http://ip_of_v6.8_cluster:9200"
},
"index": "index-2017.06"
},
"dest": {
"index": "index-es6-log"
}
}
I did reindexing from the same v6.8 cluster to a v7.3 cluster(with ReadOnlyRest es and kibana enterprise plugins installed) before without any problem.
And I encountered a similar situation when I used the snapshot endpoint before. More in:
I suspect this is a bug. Please help. Thank you
