Re: replace dead node? token -1

Jim: thanks a lot for the info. when you say old nodes sometimes hanging around as unreachable nodes when describing cluster, you mean after the new node boots up and assumes ownership of the same token, you have not manually run nodetool removeToken, right? this kind of makes sense --- since

Re: Cassandra OOM crash while mapping commitlog

Everything still runs smooth. It's really plausible that the 1.1.3 version resolved this bug. 2012/8/13 Robin Verlangen ro...@us2.nl 3 hours ago I finished the upgraded of our cluster. Currently it runs quite smooth. I'll give an update within a week if this really solved our issues.

Re: replace dead node? token -1

ok, I see, the cassandra.replace_token setting essentially executes the manual removeToken step. so the dead node should be removed. is this the old node hanging around issue that you described? https://issues.apache.org/jira/browse/CASSANDRA-3259 looks this JIRA is fixed in 1.0x already, so

Re: replace dead node? token -1

considering there is this minor old node hanging around issue, would the old T-1 approach sound more attractive? that way you don't necessarily have to remove the dead token immediately, but could come back the next day, or even a week later. T-1 would behave essentially the same in terms of

CQL3: Do boolean values need quoting in inserts?

Hi, I was following the examples on this page: http://www.datastax.com/dev/blog/whats-new-in-cql-3-0#comment-116250 In the example, a table was created as follows: CREATE TABLE altercations ( instigator text, started_at timestamp, ships_destroyed int, energy_used

Migrating to a new cluster (using SSTableLoader or other approaches)

Hi, we are trying to use SSTableLoader to bootstrap a new 7-node cassandra (v. 1.0.10) cluster with the snapshots taken from a 3-node cassandra cluster. The new cluster is in a different data centre. After reading the articles at [1] http://www.datastax.com/dev/blog/bulk-loading [2]

Re: replace dead node? token -1

I have not viewed the code, but it would seem that replace_token does not remove token, because that would spread the data and then unspread it when the new node joins. But like I said, I have not read the code. From our standpoint, we want the tokens to stay the same when possible due to the

Composite Column Slice query, wildcard first component?

Hello, Given a row like this key1 = (A:A:C), (A:A:B), (B:A:C), (B:C:D) Is there a way to create a slice query that returns all columns where the _second_ component is A? That is, I would like to get back the following columns by asking for columns where component[0] = * and component[1] = A

Re: Partial composite result limit possible?

You cannot do that in a single query. The order of columns in output is the order they are stored in. And the API can only return a contiguous range of columns. In this case I would get the larger slice and then discard columns client side. Or build a second row that has the order of the

Re: CQL3: Do boolean values need quoting in inserts?

Quoting false is correct from my reading of the Antlr grammar. Constant terms are either strings, UUID, int or long. I'm sure someone from DS will pickup the comment you made on the post and fix the example. Cheers - Aaron Morton Freelance Developer @aaronmorton
