             Summary: Optimize schema evolution for Hive
                 Key: HUDI-8182
                 URL: https://issues.apache.org/jira/browse/HUDI-8182
             Project: Apache Hudi
          Issue Type: Improvement
            Reporter: yanghao


When using MR to read Hudi, use a global InternalSchema to avoid each reader 
listing the metadata directory to obtain the InternalSchema, which places a 
significant load on the HDFS NameNode.
