I start the grid gain node using G.start(gridConfiguration), the node automatically joins the existing nodes.After this I start loading the GridCache ( which is configured to be LOCAL ).
This works fine, but is there is way to access the Grid Cache without doing the G.start(gridConfiguration), since I would like to load the LOCAL cache first and then have the node being detected by other nodes once the cache is loaded succesfully
You need to have GridGain started in order to use it's API's. After the grid is started, you can access it using GridGain.grid().cache(...) method.
What you can do, for example, is use distributed count down latch (GridCacheCountDownLatch) which is exactly the same as java.util.concurrent.CountDownLatch class. Then you can have other nodes wait on the latch while your local cache is loading. Once loading is done, you can call latch.countDown() and other nodes will be able to proceed.
More information on count-down-latch, as well as other concurrent data structures in GridGain can be found in documentation.
