---------------------------------------
Summary: Validate Parquet files written by Impala using Parquet-mr
Key: IMPALA-8197
URL: https://issues.apache.org/jira/browse/IMPALA-8197
Project: IMPALA
Issue Type: Test
Components: Infrastructure
Reporter: Csaba Ringhofer
Currently most of the insert tests write with Impala and also read back the
values with Impala to check they were written correctly. Some bugs can be
missed this way if both Impala's reader and writer logic are consistently
wrong. Reading the values back with a Parquet-mr based tool like parquet-tool
or Hive would help to catch such bugs.
