[jira] [Commented] (TEZ-4242) TEZ_DAG_ID/others loaded multiple times on various Tez UI pages

Eric Badger commented on TEZ-4242:
----------------------------------

Can anybody pick this up? It is quite wasteful for the UI to be loading these things multiple times. Unfortunately, I don't have the UI expertise to figure out where the issue is or put up a fix.

> I went into "inspect" mode on my Google Chrome browser and in the Network tab I saw that {{TEZ_DAG_ID}} is getting loaded multiple times. Here is some of the double/triple loading that I saw take place. I've sanitized the urls so it looks kind of weird. 
> *DAG Page:*
>  {{https://host:port/tez/#/dag/dag_xxxxxxxxxxxxx_xxxxxxx_x}}
>  {{TEZ_DAG_ID}} loaded 3 times
> *Vertex Page:*
>  {{https://host:port/tez/#/vertex/vertex_xxxxxxxxxxxxx_xxxxxxx_x_xx}}

> In our setup, we have both the counters and dagPlan in both {{TEZ_DAG_ID}} and {{TEZ_DAG_EXTRA_INFO}} as a local patch. However I've been testing around with a UI that has removed those and I still see the double/triple loading.
