Hi
As a part of my oozie flows I need to create "touchz" files to notify
status of each stage.
I could never get Oozie shell action to work so I wanted to see if I could
use Hive to run a hdfs/hadoop command
I had run hadoop commands inside hive but wanted to run them using -e and
-f option
Here is the result of my experiment. Hopefully it helps some of u !
HIVE -e option
==============
hive -e \!"hdfs dfs -touchz
/user/sasubramanian/gz.files.2013-06-07.files.copied.successful"
HIVE -f option
==============
Contents of mytouch.hql
!hdfs dfs -touchz
/user/sasubramanian/gz.files.${DATE_STR}.files.copied.successful
# AT runtime I replace ${DATE_STR} with todays date
hive -f mytouch.hql
Creates the file beautifully
