Hi,
I changed mapping to index so I wanted reindex. I have about 200 daily indicies that I want reindex. I used bellow command. When I ran it gave me 504 timeout error. When I checked GET /_cat/indices?v there is created about 100 copies with -reindexed at the end. But these indicies are empty and they have docs.count: 5 and nothing is happening. Their health is green and status is open. When I ran GET /_tasks?detailed=true&actions=*reindex&group_by=parents it gives me no tasks. When I check the ES log I see lot of:
org.elasticsearch.transport.RemoteTransportException: [****][*****:9300][indices:data/read/search[phase/query]]
Caused by: org.elasticsearch.search.query.QueryPhaseExecutionException: Query Failed [Failed to execute main query]
Can somebody help?
COMMAND:
POST _reindex
{
"source": {
"index": "nginxprx-*"
},
"dest": {
"index": "nginxprx"
},
"script": {
"lang": "painless",
"source": "ctx._index = 'nginxprx-' + (ctx._index.substring('nginxprx-'.length(), ctx._index.length())) + '-reindexed'"
}
}
