[jira] [Created] (IMPALA-8885) Improve parquet version metadata
error
Tim Armstrong created IMPALA-8885:
-------------------------------------
Summary: Improve parquet version metadata error
Key: IMPALA-8885
URL: https://issues.apache.org/jira/browse/IMPALA-8885
Project: IMPALA
Issue Type: Improvement
Components: Backend
Reporter: Tim Armstrong
Assignee: Tim Armstrong
The error looks like this now:
{noformat}
File 'hdfs://nn/books/books1G.csv' has an invalid version number: .99 This could be due to stale metadata. Try running "refresh s3db.books_s3".
{noformat}
It seems to be reasonably common that this happens because a non-parquet file is being queried in a parquet table.
