Hi All,
I check the documentation of Flink release 1.6, find that I can use checkpoints to resume the program either. As I encountered some problems when using savepoints, I have the following questions:
1. Can I use checkpoints only, but not use savepoints, because it can also use to resume programs. If I do so, is there any problem?
2. Checkpoint can be generated automatically, but savepoints seems can only be generated manually. I have to write a crontab to generate the savepoint, more than this, my Flink program is run on Yarn, and on the machines, only the Hadoop and Yarn are installed, so I can not use flink savepoint command to generate savepoint, and I have no authorization to install Flink on the machines.
3. Will checkpoint and savepoint merged in later releases?
Thanks very much.

Best,
Henry
