Hello All,

I have built a new 4 node cluster using riak version riak-1.1.2-1.el6.x86_64. I was reading several of the posts and inspite of doing the following, I'm still getting the preflist... error.

1. New riak version with mapred_builtins.js

-rw-r--r-- 1 root root 2936 Apr 17 05:25 /usr/lib64/riak/lib/riak_kv-1.1.2/priv/mapred_builtins.js

2. change settings for one node :

{map_js_vm_count, 24 },
{reduce_js_vm_count, 18 },
..
..
{js_max_vm_mem, 48},

3. Verify the settings

 rpc:multicall(riak_kv_js_manager,pool_size,[riak_kv_js_map]) .
{[24,24,24,24],[]}
rpc:multicall(riak_kv_js_manager,pool_size,[riak_kv_js_reduce]) .
{[18,18,18,18],[]}
4. run the map query:

For one day's data it is getting 1850 keys with a file size of 600K


Error message for more than 1 day's data

{"phase":0,"error":"[preflist_exhausted]","input":"{ok,{r_object,<

Can anyone please help?

I also built secondary indexes but it did not help....


Thanks
Mohit
