Subject: Re: Errors when using basho_bench
To: Germain Maurice <germain.maur...@linkfluence.net

Hi Germain,
The first error "{'function not
exported',[{riak_core_bucket,defaults,[]}," would occur when a bucket
does not have a "chash_keyfun" property defined. This could occur if
you have specified default bucket properties in your app.config. There
is a known issue where bucket properties defined in the app.config
file are not merged with the hard coded defaults:
http://issues.basho.com/show_bug.cgi?id=123
I'm not sure why this issue would only occur when increasing the
partition size. Were other changes made to app.config?
The second error
"{case_clause,{error,timeout}}, [{riak_kv_wm_raw,content_types_provided,2}"
occurs when a key/value pair has been inserted into Riak without a
content-type and retrieved via the REST interface. This can happen
when inserting key/value pairs with the native Erlang client or the
protobuffs client. These clients don't require that a content-type be
set. I assume the values in question were inserted by the basho bench
utility so I will look into how those values are inserted by basho bench.
Thanks,
Dan

After viewing the demonstration of basho_bench during the webinar
of the last week, we led some tests.
Here are some errors we are meeting while doing a benchmark with
basho_bench.
Big notice : when the ring partition size was 64, i never got this
kind of error (excepting a crash of a node, due to not enough
memory i think, 1,5GB RAM). But now, i have 128 partitions (see my
other message on the riak ML about the ring partition size) and
these errors occurs.
This error occured multiple times :

After shutting down the benchmark we also got this following
error, multiple times too :

Any idea about these errors ?
No problem with Webmachine ?
