I'm starting to play with ML jobs, but encountered an issue with Multi-Metric job.
It fails with
Datafeed is encountering errors extracting data: [ml-multi-low-count-test]
Search request returned shard failures; first failure: shard [[YuBCwg][logstash-general-2017.08.09]], reason [RemoteTransportException[[elasticsearch][127.0.0.1:9300]
[indices:data/read/search[phase/query]]]; nested: QueryShardException[No mapping found for [@timestamp] in order to sort on]; ]; see logs for more info
Single-Metric job with the same indexes works nice. But as far as I see, time_field is the same in both cases:
Any ideas how to debug this?
