Subject [jira] [Created] (HIVE-12080) Support auto type widening for Parquet table
Date Fri, 09 Oct 2015 19:05:05 GMT
Mohammad Kamrul Islam created HIVE-12080:

             Summary: Support auto type widening for Parquet table
                 Key: HIVE-12080
             Project: Hive
          Issue Type: New Feature
          Components: File Formats
            Reporter: Mohammad Kamrul Islam
            Assignee: Mohammad Kamrul Islam

Currently Hive+Parquet doesn't support it. It should include at least basic type promotions
short->int->bigint,  float->double etc, that are already supported for  other file

There were similar effort (Hive-6784) but was not committed. This JIRA is to address the same
in different way with little (no) performance impact.
