RaigorJiang opened a new pull request #12807: URL: https://github.com/apache/shardingsphere/pull/12807
Fixes #12806. Changes proposed in this pull request: - change metaDataMap from LinkedHashMap to ConcurrentHashMap. - add null check before get from metaDataMap. - update test cases. Description： - ConcurrentHashMap does not support null keys, so judge before get, otherwise NPE will occur. - The linkedhashMap can maintain the order of the elements, but ConcurrentHashMap cannot guarantee this, so the elements become disordered. -- This is an automated message from the Apache Git Service.
