---------------------------------------
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
