> AssertionError: Historical iterator tries to iterate WAL out of reservation
> ---------------------------------------------------------------------------
>
> Key: IGNITE-14821
> URL: https://issues.apache.org/jira/browse/IGNITE-14821
> Project: Ignite
> Issue Type: Improvement
> Reporter: Vladislav Pyatkov
> Assignee: Vladislav Pyatkov
> Priority: Major
> Time Spent: 10m
> Remaining Estimate: 0h
>
> A reason of the issue is incorrect comparison WAL pointer, that leads to
> choose not quite the last pointer for reservation before rebalance. The code
> selected the earliest WAL segment, but not the last pointer in it.
> Assuming assertion error in description:
> {code}Historical iterator tries to iterate WAL out of reservation
> [cache=SYSTEM_CACHEGROUP_LONGKEYS, reservedPointer=FileWALPointer [idx=10,
> fileOff=448674503, len=104925], historicalPointer=FileWALPointer [idx=10,
> fileOff=442844723, len=104925]]{code}
> reservedPointer is chosen incorrect, but corresponds to the valid segment
> {{idx=10}} (the same as in historicalPointer).
> A valid comparison of WAL pointers solves this issue. Segment number and
> segment offset participate in it together (look at the
> FileWalPointer#comapreTo method).
