SystemViewExporterSpi can not be properly configured

[JonasMorrissey]

The IgniteConfiguration has a method setSystemViewExporterSpi to configure a SystemViewExporterSpi. My expectation is that when I set a no-op SPI there, no JMX beans for system views will be created.

Unfortunately, this is not the case. In the method GridSystemViewManager#addStandardExporters a new new JmxSystemViewExporterSpi() is always added to the already defined SPIs:

ignite/modules/core/src/main/java/org/apache/ignite/internal/managers/systemview/GridSystemViewManager.java

Line 247 in c9bbb2f

newSpis[newSpis.length - 1] = new JmxSystemViewExporterSpi();

This behaviour was introduced for the issue https://issues.apache.org/jira/browse/IGNITE-12921 - it was claimed that configuring a custom SystemViewExporterSpi leads to non-obvious behaviour to the user, while in my opinion the exact opposite is the case. The behaviour now is non-obvious.

Two questions then:

• Is there currently a way to disable system views?
• If not, could we please make the ignite configuration have an effect?

Hi, can you clarify, why do you need to disable system views?
