[jira] [Created] (FLINK-17993) read schema from orc file

dingli123 created FLINK-17993:
---------------------------------

             Summary: read schema from orc file
                 Key: FLINK-17993
                 URL: https://issues.apache.org/jira/browse/FLINK-17993
             Project: Flink
          Issue Type: Improvement
          Components: Connectors / ORC
            Reporter: dingli123


now , if we use OrcTableSource , we must provide schema info.

In fact, the orc file already store schema info in file.

(hive --orcfiledump can see the schema info)

so OrcTableSource can read schema info from orc file
