Subject [jira] [Commented] (HIVE-3204) Windows: Fix the unit tests which contains “!<cmd>” commands (Unix shell commands)
Date Wed, 11 Jul 2012 21:29:35 GMT


Ashutosh Chauhan commented on HIVE-3204:

bq. If I understand correctly, the intent of this delete is to avoid the cascading failures.
If one test fails before cleaning up the directory, then rest of the tests which are depending
on this directory will fail automatically so we may want to keep this logic to avoid this
cascading affect.

Got your point. But still not sure if this is the best way to solve it. Creating a dir and
then immediately rm'ing doesn't look very neat. I will wait for a day before committing this
to see if someone else has an opinion on this.

>         Attachments: HIVE-3204.1.patch.txt, HIVE-3204.2.patch.txt
> 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
