Ok thanks!
If oozie runs every task as a Mapreduce, does it mean that I have to
install Hive on every machine if I want to execute Hive action?
Oozie failed with NoClassDefFoundError:
org/apache/hadoop/hive/cli/CliDriver currently.

Felix,
On #1, you typically don't want to run user code (apps) in the oozie
server. Also, by using an MR job for the shell action we get automatic load
distribution. If you need to run an action outside of the cluster, then
look at the SSH action.
On #2, whatever you print in an action will be in
Felix,
On #1, Hive actions don't produce output back to oozie. If you need the
next action to handle the output, you should point to the next action the
output directory of the hive action.
ON #2, definitely, you can add ${VAR} in your workflow configs, and provide
the the VAR=VALUE in the job.pr
I have 2 more questions:
1.Why is shell action performed as a mapreduce? Isn't it supposed to run as
a shell script on master node?
2.Is there any way to print some log within actions which can be shown in
the web console , current log seems meaningless to me ..
Thanks!

Hi, I have 2 questions:
1.How can I capture the output(a few lines) of a Hive query and pass it to
the next action(e.g. a shell script) for further processing? The
capture-output seems only supports a properties file.
2.Is it possible to manually trigger the same workflow with different
parameters
