-
Lgtm (nit: I'd rename serializeKeyspace to say addSerializedKeyspace).
bq. Can you not just wait for schema agreement in your client before going on
to the next create?
For the record, Jeremiah is right that clients are supposed to wait for schema
agreement if they want to guarantee the table creation won't fail just after
the keyspace one (or alternatively make sure both creation goes through the
same coordinator node). Of course, we shouldn't NPE internally if a user don't
respect that and that's just what this ticket is about.

Jeremiah Jordan commented on CASSANDRA-5631:
If the issue is about the node not having gotten the create KS yet. Can you
not just wait for schema agreement in your client before going on to the next
create? That is how I do things to avoid these kinds of issues.

bq. I think a fix would be to catch the NPEs above, and then, on learning about
a new keyspace, check to see if any CFs should have been created for that
keyspace.
This sounds reasonable to me. Another way would be to send the keyspace
mutation serialized along with any column families created/altered messages, so
that there will never be an NPE there in the first place. This had actually
come up before. Will have a look.

Richard Low commented on CASSANDRA-5631:
I've seen this on Cassandra 1.2.11. It happens if you create a keyspace,
following quickly by creating a column family within that keyspace. The NPE is
thrown because Schema.instance.getTableDefinition returns null for the keyspace
but it isn't checked.
In the case I saw, the node that threw the NPE had problems so it wasn't
receiving many messages - it didn't get the create keyspace message but did get
the create CF message. Even if a node doesn't have any problems, the ordering
of these messages is not guaranteed. The node will get the create keyspace
message some time later (probably about 60 seconds later when another node has
noticed the schema version is wrong) but it won't attempt to recreate the CF
unless there is a further CF change (create, update or delete) within that
keyspace. Only then is the current cached schema compared with the on disk
schema (in DefsTable.mergeColumnFamilies). It then notices the CF doesn't
exist so creates it. This could never happen, so the node won't ever create
the CF (unless it is restarted).
I think a fix would be to catch the NPEs above, and then, on learning about a
new keyspace, check to see if any CFs should have been created for that
keyspace.
I haven't tried to repro this on 2.0 but the code looks almost identical so I
would expect it to still be present.
Could someone reopen the ticket please?

I was incorrect regarding Astyanax support. I just had a classpath issue.
Anyway, I have tested in 1.2.5 and can no longer reproduce. Thanks!

Unfortunately we are using the Astyanax client which only supports up to 1.2.2.
Is there anything I can do to detect this case and retry? or work around it?
