[jira] [Comment Edited] (FLINK-15943) Rowtime field name cannot be
the same as the json field
[ https://issues.apache.org/jira/browse/FLINK-15943?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17031751#comment-17031751 ]

---------------------------------------------------------
tracking the source code:
# at org.apache.flink.table.descriptors.SchemaValidator. deriveFieldMapping(SchemaValidator.java:275), proctime/rowtime field be removed from field mapping
# at org.apache.flink.table.planner.sources.TableSourceUtil.resolveInputField(TableSourceUtil.scala:357), resolve field by field mapping
Is there a conflict between the above two？
