Error description
Hello everyone,
I have been trying to follow the examples of hooks http://docs.basho.com/riak/2.0.0/dev/using/commit-hooks/, but allways obtained an error (see below).
I am using Riak 2.0.0
These are the commands that I am using.
curl -XPUT -H "Content-Type: application/json" -d '{"props":{"precommit":[{"mod": "validate_demo", "fun": "validate"}]}}' http://127.0.0.1:8090/buckets/demo/props
curl http://localhost:8090/buckets/demo/props
curl -XPUT -H "Content-Type: application/json" -d '{scorew": 5}' http://127.0.0.1:8090/buckets/demo/keys/1
I checked list of precommit of the bucket and it is there, nevertheless obtained an error. I also checked the configuration (chkconfig) of my node (I'm using a single node) and is OK.
I'm using Mac OS X 10.10 (14A389a)
Thanks in advance,
Humberto

## Enable or disable scheduler compaction of load. By default
## scheduler compaction of load is enabled. When enabled, load

## scheduler compaction of load is enabled which will strive for a
## load distribution which causes as many scheduler threads as
## possible to be fully loaded (i.e., not run out of work). When
## scheduler utilization balancing is enabled the system will instead
## try to balance scheduler utilization between schedulers. That is,
## strive for equal scheduler utilization on all schedulers.
