Hao Chen commented on EAGLE-863:
--------------------------------
Two Bugs:
1）`siteId` is totally different from `siteName` so the query
{code}/rest/entities?query=HbaseServiceInstance[@site="siteName"]{*}&pageSize=10000{code}
is wrong, should be
{code}/rest/entities?query=HbaseServiceInstance[@site="siteId"]{*}&pageSize=10000{code}
2) Use eagle count agg query instead of agg purely in front-end with JS, for
example:
* region server alive count:
`/rest/entities?query=HbaseServiceInstance[@site="siteId" and @status="live"
and @role="regionserver"]<@site>{count}&pageSize=10000`
* region server alive count:
`/rest/entities?query=HbaseServiceInstance[@site="siteId" and @status="dead"
and @role="regionserver"]<@site>{count}&pageSize=10000`

> Currently the widgets (HDFS/HBase/YARN) on site home page (/#/site/$siteId)
> is just a mockup sample, please:
> 1) Define meaningful information in HBase widget, just for example:
> * Number of Masters (active/standby) ?
> * Number of Region Servers (live/dead)?
> 2) Define meaningful information in HDFS widget, just for example:
> * Storage/Used DFS capacity?
> * Number of DataNodes (live/dead)?
