Hi. I want to restore snapshot regardless of configuration about using coprocessor in source table.
So, I disable loading coprocessor (described in https://www.cloudera.com/documentation/enterprise/5-13-x/topics/cm_mc_hbase_service.html#concept_fx5_2mv_hv) but still fail snapshot restoring. I think, checking 'hbase.coprocessor.enabled' configuration logic is omitted during restoring snapshot.
I use hbase1.2.0-cdh5.13.0.
Confirm configuration.
but, error is occured when I try to restore snapshot 'users' table. (hostname masked)
