Tongtong Zhu created FLINK-33588: ------------------------------------ Summary: Fix Flink Checkpointing Statistics Bug Key: FLINK-33588 URL: https://issues.apache.org/jira/browse/FLINK-33588 Project: Flink Issue Type: Bug Components: Runtime / Checkpointing Affects Versions: 1.17.1, 1.18.0, 1.14.6, 1.15.2, 1.17.0, 1.16.0, 1.14.5 Reporter: Tongtong Zhu Fix For: 1.19.0, 1.18.1
When the Flink task is first started, the checkpoint data is null due to the lack of data, and Percentile throws a null pointer exception when calculating the percentage. After multiple tests, I found that it is necessary to set an initial value for the statistical data value of the checkpoint when the checkpoint data is null (i.e. at the beginning of the task) to solve this problem. -- This message was sent by Atlassian Jira (v8.20.10#820010)
