[jira] [Comment Edited] (ARROW-10762) [Java] Configuration does not
provide a mapping for array column
[ https://issues.apache.org/jira/browse/ARROW-10762?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17242879#comment-17242879 ]

------------------------------------------------------------
[~dclong] Sure we have a default mapping, which can be found here (https://github.com/apache/arrow/pull/8597/files#diff-5f6ecfada9677653fcba498dced5daec420625828ee6e726fc1fcb10f9bd0b99). If we do not specify a customized mapping, the default one will be used.
However, it seems the default mapping failed to process your data. If you could provide more details, maybe we can help you do some more investigations.
