HI, I have a question.
I installed hdp version 2.6.2 and run flink application with hdfs.
Flink use hdfs for checkpoint.
"Number of Blocks Pending Deletion" is increaseing ( over 40,488,485 ).
So I have two questions.
1. Is there a problem if it continues to increase?
For reference, Checkpoint is running every 15 seconds. Checkpoint do create many blocks and delete many blocks
2. Is there any way to reduce the "Number of Blocks Pending Deletion"?
