1.WHAT IS CHECKPOINTS IN HADOOP 2.WHERE IT WILL STORE 3.IS EDITLOG AND CHECKPOINT IS SAME ?

[#1 · Accepted solution]

Checkpointing is the process of merging editlogs with base fsimage. This will be stored in namenode metadata directories. Its not the same as editlog, since editlog has the changes that you make to HDFS.
