[jira] [Updated] (HIVE-15437) avro tables join fails when - tbl
join tbl_postfix
[ https://issues.apache.org/jira/browse/HIVE-15437?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Yongzhi Chen updated HIVE-15437:
--------------------------------
Attachment: HIVE-15437.1.patch
The root cause is when getSchema for avro table, it compare splits path with table path by only matching same start string. This makes table1_1 got table1's schema, then cause the Exception later.
Attach the patch to fix the issue.
