Hi @lalala ,   This behavior was caused by the csv module when impala is using it to export the data.       # csv.writer expects a file handle to the input.     # cStringIO is used as the temporary buffer.     temp_buffer = StringIO()     writer = csv.writer(temp_buffer, delimiter=self.field_delim,                         lineterminator='\n', quoting=csv.QUOTE_MINIMAL)     writer.writerows(rows)   Seems to be we cannot change this since it is needs to modified at code level.   [1].  https://github.com/apache/impala/blob/014c455aaaa38010ae706228f7b439c080c0bc7d/shell/shell_output.py#L64 ...

Hi,   What is the query you are using to read the data from table? can you attach its "query profile" and coordinator logs to have a look?   Regards, Chethan YM ... View more

Hi,   Can you provide these below details to understand the issue:   1. Initially from where you created the table in hive or impala? 2. Provide the DDL of the table that you are trying to query from impala.      # show create table <table-name>; 3. list the files from hdfs path ( you will see the table path in the DDL def. )     # hdfs dfs -ls /table/path/ 4. Are you able to access the same table data from hive?( if you are facing the issues from impala?  vice versa) 5. Go to HS2 logs/coordinator logs copy the entire error stack trace for the query that is failing and paste here.   I think these are the basic details needed for analysing the issue.   Regards, Chethan YM ...
