EdColeman opened a new pull request, #4567:
URL: https://github.com/apache/accumulo/pull/4567
Adds a admin command `serviceStatus` to print service counts and hosts, with
resource groups when appropriate to stdout.
To run the command:
` > accumulo admin serviceStatus [--noHosts ] [--json]`
The noHost option output provides a summary count
The --json option provides unformatted json output (the --noHost option is
ignored)
Sample output:
<details>
<summary>Summary (service counts only)</summary>
```
> accumulo admin serviceStatus --noHosts
