[jira] [Updated] (PARQUET-971) Parquet file can not be read properly when it starts with an underscore

["Jurgis Pods (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/PARQUET-971?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jurgis Pods updated PARQUET-971:
--------------------------------
    Description: 
When a Parquet file starts with an underscore,
- parquet-tools head <filename> fails
- Hive/Impala will not show any data in external tables

If the underscore is deleted, everything works as expected. I don't know if this is expected behaviour - but if so, it should probably be documented.
