----------------------------------
Summary: Wrong index information will be obtained after the
downstream failover in hybrid full mode
Key: FLINK-29238
URL: https://issues.apache.org/jira/browse/FLINK-29238
Project: Flink
Issue Type: Bug
Components: Runtime / Network
Affects Versions: 1.16.0
Reporter: Weijie Guo
Fix For: 1.16.0
Hybrid shuffle relies on the index to read the disk data. Since the spilled
data may be consumed from memory, the readable status is introduced. For the
readable buffer, FileDataManager does not do the pre-load. However, when the
downstream fails, the previous readable status will be used incorrectly,
resulting in that some buffer cannot be read correctly.
