<h3><u>#troubleshooting</u></h3><br><strong>@pradeepgv42: </strong>I created a 
table with following tagOverrideConfig

```  "tenants": {
    "broker": "DefaultTenant",
    "server": "DefaultTenant",
    "tagOverrideConfig": {
      "realtimeConsuming": "DefaultTenant_REALTIME",
      "realtimeCompleted": "DefaultTenant_OFFLINE"
    }
  },```
But the restapi /tables/{tableName} only shows
```"tenants": {
      "broker": "DefaultTenant",
      "server": "DefaultTenant"
    },```
Wondering if this config is coupled with something else?<br><strong>@g.kishore: 
</strong>@npawar ^^ any docs on this?<br><strong>@g.kishore:

 we should add the real-time segment relocator here<br><strong>@pradeepgv42:

 </strong>I am using “LowLevel” consumer<br><strong>@npawar: </strong>can you 
share the whole table config?<br><strong>@pradeepgv42: </strong>```{

}```<br><strong>@npawar: </strong>also check if there’s anything in the logs 
when you did a POST for the table config<br><strong>@pradeepgv42: </strong>let 
me check that<br><strong>@npawar: </strong>also, was this during 1st time 
creation, or update?<br><strong>@g.kishore: </strong>btw, I don't think there 
is anything wrong with the output.<br><strong>@pradeepgv42: </strong>@npawar 
First time I had tagsOverrideConfig but consumer type was “lowlevel”, so I did 
AddTable again where I changed consumer type from lowlevel to LowLevel
Not sure if that would effect?<br><strong>@npawar: </strong>that property is 
case insensitive, so both calls should be treated the same<br><strong>@npawar: 
</strong>i could reproduce, i’ll investigate<br><strong>@pradeepgv42: 
</strong>nice thanks<br><strong>@npawar: </strong>how are you starting the 
Controller? @pradeepgv42<br><strong>@pradeepgv42: </strong>bin/pinot-admin.sh   
 StartController -configFileName  &lt;controllerConfig&gt;<br><strong>@npawar: 
</strong>cool, there’s a controller property called tenantIsolation which by 
default is true. that prop overrides the tenant config.<br><strong>@npawar: 
</strong>we can set it to false in the controller conf. looking for the exact 
property key<br><strong>@pradeepgv42: </strong>would that effect anything else? 
yeah not able to find a way to override it through controller 
config<br><strong>@npawar: 
</strong>`cluster.tenant.isolation.enable=false`<br><strong>@npawar: 
</strong>try this<br><strong>@pradeepgv42: </strong>trying 
it..<br><strong>@pradeepgv42: </strong>it worked, I can see the 
tagsOverrideConfig from the rest-api, I will wait for a bit and check if the 
segments are moving<br><strong>@pradeepgv42: </strong>What does the 
`cluster.tenant.isolation.enable` variable do?<br><strong>@pradeepgv42: 
</strong>it assumes single tenant?<br><strong>@npawar: </strong>Segments are 
moved by a periodic task on the controller. so you might have to wait upto an 
hour to see the completed segments moving. it runs every 
hour<br><strong>@npawar: </strong>yes.. that property assumes single tenant 
called “DefaultTenant”<br><strong>@g.kishore: </strong>@npawar do we still need 
that property, looks like its not adding any value<br><strong>@g.kishore: 
</strong>maybe it was added to roll out the feature in a controlled 
manner<br><strong>@npawar: </strong>actually i dont know why we have that prop. 
i can check and remove it if i dont find any use<br><strong>@g.kishore: 
</strong>cool, lets create an issue and remove it<br><strong>@pradeepgv42: 
</strong>makes sense, thanks, will check a bit later<br><strong>@npawar: 
</strong>created issue:
