Recently installed fault-injection techniques are making quality assurance processes yet more rigorous.
In a previous installment of our series about quality assurance inside Cloudera, we described the fault-injection frameworks (AgenTEST and Sapper) that Cloudera Engineering has devised. The fault-injection framework starts and stops injections, to determine when and how they should occur, respectively.
On that occasion, we presented a number of disk-related injections implemented in AgenTEST, including:
- BurnIO: Runs disk-intensive processes,
