Hi,
I finally found the reason for this message: Although the bucket was
initialized with r=1, the java client silently appended a "r=2" to all
fetches which caused this message.
The combination of two things really cost me a lot of time to find the
reason for this:
* the error message from riak complains about wrong write parameters but
in fact the read parameter was wrong.
* the java client library silently attaches a "r=2" to all read queries
and I didn't find anything in the documentation about this. Is this
intended or a bug?
Setting the used apache http client into trace really helped a lot,
maybe you should add something about this into the java client
documentation.

Hi Russell,
I'm using riak 1.2 and the client version is version 1.0.5 and
concerning HTTP and PB, I tried both.

Hi Mark,
thanks for looking into this.
I'm using the riak-java-client for accessing riak,
Are you using HTTP or PB, please? And can you let me know the version,
too?
Thanks
Russell
the bucket is created with the following code:
msgBucket = riakClient.createBucket(MSG_BUCKET_ID).
nVal(1).w(1).dw(1).pw(1).
execute();
and the write operation is:
msgBucket.store("Mailbox|" + messageDto.getReceptor(),
createMailbox(messageDto)).execute();
without doing any modification of w/dw/pw for the single write.

Hi Ingo
I just built a single node Riak 1.2 from source on my laptop, cranked
the n, w, dw, and pw values down to "1", and was able to write
successfully via curl. For the sake of completeness, I attempted to
write with "w=2" and was able to throw the "Specified w/dw/pw values
invalid for bucket n value of 1" error that you reported.
Any chance you have some app code that's changing the W value? Can you
share the specifics of the request that's failing?

Hi Ingo,
Sorry for the holdup here.
Riak shouldn't be throwing this error if all your R and W values are
set to "1". Are you running Riak 1.2?

Hi List,
I'm trying to set the n-val to 1 for my single-node test server
but do
always fail with the following error:
Specified w/dw/pw values invalid for bucket n value of 1
This is my bucket configuration:
{"props":{"allow_mult":false,"basic_quorum":false,"big_vclock":50,"chash_keyfun":{"mod":"riak_core_util","fun":"chash_std_keyfun"},"dw":1,"last_write_wins":false,"linkfun":{"mod":"riak_kv_wm_link_walker","fun":"mapreduce_linkfun"},"n_val":1,"name":"messages","notfound_ok":true,"old_vclock":86400,"postcommit":[],"pr":1,"precommit":[],"pw":1,"r":1,"rw":1,"small_vclock":50,"w":1,"young_vclock":20}}
I can't see what's wrong with it, maybe someone can shed a light.
Regards,
Ingo
