Oozie shell Action - Running hive from shell issue

Question

Based on a condition being true I am executing hive -e in shell script.It works fine.When I put this script in Shell action in Oozie and run ,I get a scriptName.sh: line 42: hive:command not found exception.

I tried passing the < env-var >PATH=/usr/lib/hive< /env-var> in the shell action, but I guess I am making some mistake there,because I get the same error scriptName.sh: line 42: hive:command not found

Edited: I used which hive in the shell script. Its output is not consistent.I get two variations of output :
1. /usr/bin/hive along with a Delegation token can be issued only with kerberos or web authentication Java IOException."

2. which : hive not in {.:/sbin:/usr/bin:/usr/sbin:...}

Answer 1

Ok finally I figured it out .Might be a trivial thing for experts on Shell but can help someone starting out.

1. hive : command not found It was not a classpath issue.It was a shell issue.The environment i am running in is a korn shell (echo $SHELL to find out). But the hive script(/usr/lib/hive/bin/hive.sh) is a bash shell.So i changed the shebang (#! /bin/bash) in my script and it worked.

2.Delegation Token can only be issued with kerberos or web authentication. In my hive script i added SET mapreduce.job.credentials.binary = ${HADOOP_TOKEN_FILE_LOCATION} HADOOP_TOKEN_FILE_LOCATION is a variable that holds the location of jobToken.This token needs to be passed for authentication of access to HDFS data(in my case,an HDFS read operation,through Hive Select query) in a secure cluster.

Obviously, u miss shell environment variables.

To confirm it, use export in called shell by oozie.

If u use oozie call shell, a simple way is use /bin/bash -l your_script .

PS. PATH is a list of directories, so u need append ${HIVE_HOME}/bin to your PATH not ${HIVE_HOME}/bin/hive .
