Hello,

I would like to know, from where elasticsearch is reading status data and info about indexes etc.

I had a problem with elasticsearch node, who no longer waated to join the cluster. There were errors like that:

_**[2018-09-03T15:23:30,202][ERROR][i.n.u.c.D.rejectedExecution] Failed to submit a listener notificatio**_  
_ **n task. Event loop shut down?** _

Then I deinstalled elasticsearch form that node. I deleted data folder: /var/lib/elasticsearch and /etc/elasticsearch folder.

I started a new installation of elasticsearch and started it as standalone. No info about other cluster nodes in config file. It went OK, but immediatel it started issuing messages about indexes, that are located in cluster.

..  
**_[2018-09-04T10:07:03,606][INFO][o.e.c.m.MetaDataMappingService] [re62nWZ] [win\_deflector/Ue-Z\_5XnQo2WGkXdWdR9dg] update\_mapping [message]_**  
**_[2018-09-04T10:08:13,613][INFO][o.e.c.m.MetaDataMappingService] [re62nWZ] [win\_deflector/Ue-Z\_5XnQo2WGkXdWdR9dg] update\_mapping [message]_**  
**_[2018-09-04T10:08:18,622][INFO][o.e.c.m.MetaDataMappingService] [re62nWZ] [graylog\_deflector/gnPLQglSR-G51k98Bj3Naw] update\_mapping [message]_**  
**_.._**

And the command \_cat/shards lists only deflector shards:

> **_unix\_deflector 0 p STARTED 163 157.2kb 192.168.10.207 re62nWZ_**  
> **_unix\_deflector 0 r UNASSIGNED_**  
> **_graylog\_deflector 1 p STARTED 2138 1mb 192.168.10.207 re62nWZ_**  
> **_graylog\_deflector 1 r UNASSIGNED_**

So my question is from where is the elasticsearch getting all this data about shards and indexes, as I deleted most of the info. ?
