Flood of o.e.d.c.m.IndexNameExpressionResolver in log

[pandamasta]

Hi,

In log there is a flood of warning

elasticsearch_1 | [2021-11-30T10:45:10,645][DEPRECATION][o.e.d.c.m.IndexNameExpressionResolver] [elasticsearch] this request accesses system indices: [.kibana_1], but in a future major version, direct access to system indices will be prevented by default
Cheers

Hello @pandamasta

This flood of errors is an opendistro bug, which prolongs those errors several times.

Checking inside the repository they have an issue about it in which they are working:
opensearch-project/OpenSearch#1108

Within it they give the idea of disabling that level of log as workaround, but it does not seem like a good solution because it can hide other important things.

If you don't have a large number of messages, I recommend to ignore it. I did a test and did not get too many messages.

Regards
