I think Oozie Shell action is already taken care of this. There should not be
any issue.
Please let us know if you find any.

Hello Mohammad.
Ty for your answer. There is no errors in fact. I'm just wondering this
question.
If I want to interact with hdfs or hbase or hive in a shell from an oozie
shell action, how can I use the env variable HADOOP_TOKEN_FILE_LOCATION ?
Is the usage of this env variable the solution ?
BR.
