Subject Re: Redefine yarn.application.classpath value
Date Sun, 06 Mar 2016 19:47:58 GMT
Hi Dejan, thanks for your answer and sorry for taking too long to response.

I have this line in yarn-env.sh:
export YARN_CONF_DIR="${YARN_CONF_DIR:-$HADOOP_YARN_HOME/conf}"

I changed to
export YARN_CONF_DIR=${HADOOP_CONF_DIR}

But it didn't change anything.

I also take a look at $HADOOP_HOME/etc/hadoop searching for
HADOOP_CONF_DIR, as you already suggested Dejan, and i founded this on
hadoop-env.sh:
export HADOOP_CONF_DIR=${HADOOP_CONF_DIR:-"/usr/local/hadoop/etc/hadoop"}

Those are the only ocurrences that i could find.

I'm starting to believe that i'm making some huge mistake, because i keep
modifyng configuration files and the command *yarn classpath* is always
showing me the same output.

Please, any help would be really appreciated !!

Bye!
Jose
