-------------------------------------------
Summary: Need to validate that SPIs are started only once
Key: IGNITE-2708
URL: https://issues.apache.org/jira/browse/IGNITE-2708
Project: Ignite
Issue Type: Improvement
Components: general
Reporter: Valentin Kulichenko

If one uses the same instance of {{IgniteConfiguration}} more than once, it
doesn't work because SPIs have lifecycle and can be started only once.
Currently this causes hang on start which is counterintuitive.
We should add a validation step to {{GridSpiAdapter}} that will check that the
SPI was never started before. Its {{spiStart()}} method should set some flag
there or throw exception if it has already been set. All internal SPI
implementations should be changed to call {{super.spiStart()}} as first
statement.
