摘要

Fault tolerant mechanisms are essential to provide reliable feature for distributed systems. Checkpoint and Recovery is a widely used technique that consists on saving data states for a fast recovery in case of failure. On Apache Hadoop and Apache Spark - distributed high performance frameworks -, checkpoint aims to help on recovery steps after failures. However, wrong configuration of checkpoint attributes can degrade system performance and reliability, thus losing checkpoint purpose. This work proposes a dynamic architecture for checkpoint based on system monitoring and alerts. In order to avoid checkpoint problems on Hadoop and Spark, one implementation of dynamic mechanism is defined for each framework.
