hi guys,  
In 7.2.1 elasticsearch there is a bug with generating WARN messages in case if refresh interval enabled.  
 ![image](https://us1.discourse-cdn.com/flex019/uploads/mauve_hedgehog/original/1X/f99294c8010d1f4072ef0b32c6e066064e331471.png)  
` {"log":"[2019-12-04T16:44:53,902][WARN][o.e.d.s.a.b.h.DateHistogramAggregationBuilder] [odfe-node1] [interval] on [date_histogram] is deprecated, use [fixed_interval] or [calendar_interval] in the future.\n","stream":"stdout","time":"2019-12-04T16:44:53.9022652Z"}`

Messages go into log file witch causing on file size. In my case, the log file size was increased up to 8GB in a few hours.

This bug was fixed in 7.4.0 version.  
Is there some temporary solution for setup retention for log file?  
Thanks in advance.
