> See HBASE-21601 for context.
> I looked at the code a bit but it will take a while to understand, so for now
> I'm going to mitigate it by skipping such records. Given that this record is
> bogus, and the lengths are intact, for this scenario it's safe to do so.
> However, it's possible I guess to have a bug where skipping such record would
> lead to data loss. Regardless, failure to split the WAL will lead to even
> more data loss in this case so it should be ok to handle errors where the
> structure is correct but cells are corrupted.
