Sanket, I can't speak to the output of cluster-info with regard to the precomit hook.
If you save an object to the "test_kv" bucket, does rtriggers:pre_all() get called? I have confirmed that precommit hooks are *NOT* triggered for buckets where "write_once" is true, and filed the following docs issue: https://github.com/basho/basho_docs/issues/2076 -- Luke Bakken Engineer lbak...@basho.com On Mon, May 16, 2016 at 8:20 AM, Sanket Agrawal <sanket.agra...@gmail.com> wrote: > Shouldn't precommit body show up in cluster-info first before we try to test > it with an object?
