Sylvain Lebresne commented on CASSANDRA-6959:
---------------------------------------------
I haven't looked at the CommitLog assertion (I'll let somewhat more up to date
on the last commit log changes look at it), but regarding the 2nd one, the one
in ExtendedFilter, that's because the test tries to use a 2ndary index before
it's creation has been propagated to all nodes. More precisely, the {{select
count(*) from ks.cf WHERE col1='asdf'}} of the test reaches the coordinator
node1, which has seen the index creation and so the query is considered valid,
but when the underlying RangeCommand reaches the 2nd node, that one doesn't yet
know about the index and so fallback to a sequential scan, but we don't
currently support that kind of sequential scan with filters hence the exception
(and truly, that was not what the user asked about anyway). If you add a small
sleep after the index creation, that exception goes away in particular. The
current status quo (CASSANDRA-5886) is that it's the client job to check for
schema agreement if need be and not query a table/index that is not fully
propagated, and in that sense, it is the test that should be fixed. Note that
I'm not against trying to have a clearer error message but I'm not really sure
there's a much better place for this, so I did added a somewhat more explicit
message to the assertionError which hopefully is good enough.
