Kanna Karanam created HIVE-3204:
-----------------------------------
Summary: Windows: Fix the unit tests which contains “!<cmd>”
commands (Unix shell commands)
Key: HIVE-3204
URL: https://issues.apache.org/jira/browse/HIVE-3204
Project: Hive
Issue Type: Sub-task
Components: Tests, Windows
Affects Versions: 0.10.0
Reporter: Kanna Karanam
Assignee: Kanna Karanam
Fix For: 0.10.0
Possible solution 1: (Preferred one)
!<Unix cmd | Windows cmd> => Keeping the same syntax. Hive uses Java runtime to
launch the shell command so any attempt to run windows commands on Unix will
fail and vice versa.
To deal with unit tests. Unix commands in each .q file will be modified as
shown below. I will filter out the !commands which can’t be run on the current .
Original entry in.q file:
!rm -rf ../build/ql/test/data/exports/exim_department;
It will be replaced with the following entries.
UNIX::!rm -rf ../build/ql/test/data/exports/exim_department;
WINDOWS::!del ../build/ql/test/data/exports/exim_department
Possible solution 2:
Provide a Shell UDF library(JAVA Based code)to support platform independent
shell functionality
Cons –
1) Difficult to provide full shell functionality
2) Takes long time
3) Difficult to manage
