I don't know what is environmentContext lock, can you explain more? Or provide a example.

apache/hive#3888 changes HMS API , we can use "hive_metastoreConstants.EXPECTED_PARAMETER_KEY" or "hive_metastoreConstants.EXPECTED_PARAMETER_VALUE" to commit instead of 4 HMS calls

It seems there are some problem for this feature, see the discussion in: https://issues.apache.org/jira/browse/HIVE-26882

Let's keep an eye on it.
