kezhenxu94 edited a comment on issue #4191: ttl clean data error URL: https://github.com/apache/skywalking/issues/4191#issuecomment-571593150 > New to me @wu-sheng do you mean: ``` 2020-01-07 12:05:09,398 - org.elasticsearch.client.RestClient -79208733 [I/O dispatcher 1] WARN [] - request [PUT http://elasticsearch:9200/endpoint_relation_server_side_month-202001?master_timeout=30s&timeout=30s] returned 1 warnings: [299 Elasticsearch-6.8.1-1fad4e1 "[types removal] The parameter include_type_name should be explicitly specified in create index requests to prepare for 7.0. In 7.0 include_type_name will default to 'false', and requests are expected to omit the type name in mapping definitions."] ``` it's just warning, the root cause is creating a index twice: ``` {"error":{"root_cause":[{"type":"resource_already_exists_exception","reason":"index [endpoint_relation_server_side_month-202001/0d0aytdDRCm8jvpejAf-WA] already exists","index_uuid":"0d0aytdDRCm8jvpejAf-WA","index":"endpoint_relation_server_side_month-202001"}],"type":"resource_already_exists_exception","reason":"index [endpoint_relation_server_side_month-202001/0d0aytdDRCm8jvpejAf-WA] already exists","index_uuid":"0d0aytdDRCm8jvpejAf-WA","index":"endpoint_relation_server_side_month-202001"},"status":400} ``` I suspect that there may be something wrong with the TTL config
