As developers, we need to accept the reality that things do go wrong and debugging is required. This section is going to equip you to handle such situations effectively and efficiently. The first thing is to understand two root mantras of the programming world:
Work as if everything that could break will break
Anything that could break can be fixed
Having accepted the reality, let's address the situation first by understanding what could fail and then have a clear understanding of where we should start the analysis to help us handle any situation with the Storm cluster.
