In my case, even though I have uris in the supplied > config to connect to remote MS (which eventually happens), the static call > creates objectstore, which is undesirable. > 2) It breaks compat - old metastores do not support this call so new clients > will fail, and there's no workaround like not using a new feature because the > static call is always made -- This message was sent by Atlassian JIRA (v6.3.4#6332)
