Jeff Jirsa commented on CASSANDRA-13973:
----------------------------------------
Thanks for the feedback [~slebresne]. I really appreciate you taking the time
to respond. The risky feeling here is why I'm moving slow on this myself - it
seems straightforward, but obviously the potential for unexpected surprises
here is pretty high.
Better messaging on that assert makes a lot of sense. Also good to see the
second confirmation that changing {{column_index_size_in_kb}} is a good
workaround, the drawback is that it's instance-wide, so if you have just a
handful of wide rows (like this user, the histogram shows their 99% size is
less than 1MB, but their max size is 394GB), you suffer a disk penalty on all
keyspaces/tables/rows in order to not crash on the one bad row.
[~dankinder] if you need to unblock yourself right now, changing
{{column_index_size_in_kb}} on your instance to 256k (7G of index data needs to
go under 2G in size, so multiplying factor of 4) PROBABLY works past this
issue, but expect a bit more disk IO (particularly reads) after the change

> URL: https://issues.apache.org/jira/browse/CASSANDRA-13973
> Project: Cassandra
> Issue Type: Bug
> Components: Compaction
> Reporter: Dan Kinder
> Assignee: Jeff Jirsa
> Priority: Major
> Fix For: 3.0.x, 3.11.x, 4.x
>
>
> After an upgrade from 2.2.6 to 3.0.15 (sstable version la to mc), when I try
> to run upgradesstables, most of them upgrade fine but I see the exception
> below on several nodes, and it doesn't complete.
> CASSANDRA-12717 looks similar but the stack trace is not the same, so I
> assumed it is not identical. The various nodes this happens on all give the
> same trace.
> Might be notable that this is an analytics cluster with some large
> partitions, in the GB size.
