All nodes have search=on in the riak.conf and I see the Java process.

** exception exit: {{nodedown,'riak@10.127.137.185'},
{gen_server,call,
[{riak_core_metadata_hashtree,
'riak@10.127.137.185'},

in call from yz_kv:is_metadata_consistent/1 (src/yz_kv.erl, line 433)
Based on the output of those we can debug further.
