Ashutosh Chauhan commented on HIVE-3204: ---------------------------------------- [~kanna...@microsoft.com] : Few comments: * I see that you have added temp subdir in few places and then do rm immediately. As you noted I believe this is the case when dir doesnt exist dfs -rmr throws some exception while !rm -rf was not. If thats the case then I think we should remove !rm -rf statement altogether since there is no point in removing non-existent dir. Also, its confusing to create a dir and then remove it immediately. * In few .q.out files, output has changed from 1 2 4 to "Found 3 items" this looks suspicious. Do you know why that has happened ? * Try to minimize white space changes in patch. There were quite bunch of them in this patch. > 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 > > Attachments: HIVE-3204.1.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 -- This message is automatically generated by JIRA.
