[jira] Created: (HIVE-188) hive CLI should quit when stdout is closed

hive CLI should quit when stdout is closed
------------------------------------------

                 Key: HIVE-188
                 URL: https://issues.apache.org/jira/browse/HIVE-188
             Project: Hadoop Hive
          Issue Type: Bug
          Components: Clients
            Reporter: Zheng Shao


bin/hive -e 'select * from a_big_table;' | head

The process does not end after printing out the first 10 lines.

This is probably because System.out.println is not checking errors. We need to manually call boolean System.out.checkError() to know if the output is closed or not.

[jira] Commented: (HIVE-188) hive CLI should quit when stdout is closed

Joydeep Sen Sarma commented on HIVE-188:
----------------------------------------

+1

interesting bug. i guess this affects any place where we call println() - but probably this is the most significant one. Hadoop FSShell (for example) seems to go throw a common library for all printstream IO
