+ Assert.assertTrue(store.fs.getConf() == store.fsConf);
{code}
I think we should validate that fs instance isn't same before restarting.
{code}
// Pseudo code
FileSystem beforeRestartFs = store.fs;
store.stop();
store.start();
Assert.assertNotEquals(store.fs, beforeRestartFs)
{code}
> FileSystemRMStateStore should disable FileSystem Cache to avoid get a
