> Fix member status logic when directory specified
> ------------------------------------------------

> Key: GEODE-9478
> URL: https://issues.apache.org/jira/browse/GEODE-9478
> Project: Geode
> Issue Type: Bug
> Components: core
> Reporter: Mario Salazar de Torres
> Assignee: Mario Salazar de Torres
> Priority: Major
>
> As result of doing some tests with the status GFSH command in a cloud native
> environment, it has been noticed that when --dir option, the internal logic,
> if API attachment is enabled, tries to access the JMX interface to query the
> server status.
> And in order to obtain the JMX URL, the logic tries to attach to the member
> with its PID. But, the thing is that in the problematic use case, both the
> member and Gfsh/equivalent app using Gfsh API are in different containers,
> and such containers do not share the PID namespace.
> When both member and the status requesting application have different PIDs
> the request fails given that the requesting application can't locate the
> member PID on its namespace, sending a SIGQUIT (in a unix-like env) and
> throwing an exception stating "no such process...". And if the internal logic
> notices that the process couldn't be found, instead of failing over the
> FileProcessController, it propagates the exception, causing the status
> request to fail.
> Additionally it has been observed that with the current logic, the status
> command success if and only if the PID of the application executing the
> status command, and the PID of the member are the same. I.E: PID 1
> The reason for that apparently is that there is some check in the JVM
> attachment API that verifies if the PID of the JVM you are trying to attach
> is the same as yours. If that's the case, it supposes that you are trying to
> attach to yourself and throws an exception.
> In that case, the exception is catched by the internal logic and the status
> request failovers to the FileProcessController.
