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
