Hi Our Kudu test environment got unresponsive yesterday for unknown reason. It has three tablet servers and one master. It's running in AWS on quite small host machines, so maybe some node ran out of memory or something. It has happened before with this setup. Anyway, after we restarted kudu service, we couldn't do any selects. From the tablet server UI I could see it was initializing and bootstrapping tablets. It took many hours until all tablets were in RUNNING-state.
My question is where can I find information about these background operations? I want to understand what happens in situations when some node is offline and then comes back up after a while. What is tablet initialization and bootstrapping, etc. -- Br. Janne Keskitalo, Database Architect, PAF.COM For support: [email protected]
