Description

HConnectionManager.isTableAvailable() the SERVER_QUALIFIER for each region, including the offline split parent.

In case of hbck META recovery or snapshots clone/restore an offline parent will never be assigned (since should stay offline). In this case HBaseAdmin.waitUntilTableIsEnabled() used by enable() and cloneSnapshot() will wait until the timeout is expired.
