             Summary: Missing \n every 1024 or 2048 lines when exporting output from shell to a file
                 Key: IMPALA-10447
                 URL: https://issues.apache.org/jira/browse/IMPALA-10447
             Project: IMPALA
          Issue Type: Bug
          Components: Clients
    Affects Versions: Impala 4.0
            Reporter: Andrew Sherman
            Assignee: Andrew Sherman


When Impala shell exports output to a file, for example 
{code:java}
impala-shell -B  -V  -q "select * from tpcds.item" -o filex.csv --output_delimiter=';'
 {code}
then every 1024 (or maybe 2048) rows a newline is missing.

I think the problem is here: https://github.com/apache/impala/blob/9bb7157bf014282c95ab3e233b80d77e00c95b52/shell/shell_output.py#L119
where we now use write instead of print to output the rows.
It may be sufficient to add a
{code}
out_file.write('\n')
{code} 
here
