[jira] [Created] (FLINK-29238) Wrong index information will be obtained after the downstream failover in hybrid full mode

Weijie Guo created FLINK-29238:
----------------------------------

             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.
