-source solution. In Hadoop, JobTracker generally does not have to solve the error tolerance of JobTracker because the failure probability of JobTracker is much lower than that of NameNode. In the latest version 4.2.0, Cloudera provides a complete set of JobTracker HA solutions. This article will introduce this solution. Before introducing the CDH solution, briefly introduce the basic workflow of JobTracker HA, which can be summarized as follows: (1)
