Roman Khachatryan commented on FLINK-24433:
-------------------------------------------
I suspected that changelog state backend might have left some files undeleted.
But when checking the logs (e2e), I see it wasn't enabled.
However, both failures selected exactly the same values:
{code:java}
find ./ -type f -exec grep 'Randomly ' {} \; | less
PseudoRandomValueSelector [] - Randomly selected false for
execution.checkpointing.unaligned
PseudoRandomValueSelector [] - Randomly selected PT2S for
execution.checkpointing.alignment-timeout
PseudoRandomValueSelector [] - Randomly selected false for
state.backend.changelog.enabled
PseudoRandomValueSelector [] - Randomly selected false for
taskmanager.network.memory.buffer-debloat.enabled
PseudoRandomValueSelector [] - Randomly selected false for
execution.checkpointing.unaligned
PseudoRandomValueSelector [] - Randomly selected PT2S for
execution.checkpointing.alignment-timeout
PseudoRandomValueSelector [] - Randomly selected false for
state.backend.changelog.enabled
PseudoRandomValueSelector [] - Randomly selected false for
taskmanager.network.memory.buffer-debloat.enabled
{code}
This probably suggests that some test creates too much back-pressure and can
hang without Unaligned checkpoints or Buffer debloating.
I didn't check the other phases though.
