Yongzhi Chen updated IMPALA-7087: --------------------------------- Attachment: binary_decimal_precision_and_scale_widening.parquet > Impala is unable to read Parquet decimal columns with lower precision/scale > than table metadata > ----------------------------------------------------------------------------------------------- > > Key: IMPALA-7087 > URL: https://issues.apache.org/jira/browse/IMPALA-7087 > Project: IMPALA > Issue Type: Sub-task > Components: Backend > Reporter: Tim Armstrong > Assignee: Yongzhi Chen > Priority: Major > Labels: decimal, parquet > Attachments: binary_decimal_precision_and_scale_widening.parquet > > > This is similar to IMPALA-2515, except relates to a different precision/scale > in the file metadata rather than just a mismatch in the bytes used to store > the data. In a lot of cases we should be able to convert the decimal type on > the fly to the higher-precision type. > {noformat} > ERROR: File '/hdfs/path/000000_0_x_2' column 'alterd_decimal' has an invalid > type length. Expecting: 11 len in file: 8 > {noformat} > It would be convenient to allow reading parquet files where the > precision/scale in the file can be converted to the precision/scale in the > table metadata without loss of precision. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-all-unsubscr...@impala.apache.org For additional commands, e-mail: issues-all-h...@impala.apache.org
