------------------------------------

             Summary: java.lang.IllegalStateException: tez.task.scale.memory.reserve-fraction is set at the scope of VERTEX, but it is only valid in the scope of AM
                 Key: TEZ-3446
                 URL: https://issues.apache.org/jira/browse/TEZ-3446
             Project: Apache Tez
          Issue Type: Bug
    Affects Versions: 0.8.3
            Reporter: Pengcheng Xiong


I ran hive on tez in single node mode. My paths are like this
{code}
export TEZ_HOME=/Users/pxiong/Projects/runTez/apache-tez-0.8.3-src/tez-dist/target/tez-0.8.3
export TEZ_CONF_DIR=$TEZ_HOME/conf
export HADOOP_CLASSPATH="$TEZ_HOME/*:$TEZ_CONF_DIR:$TEZ_HOME/lib/*:$HADOOP_CLASSPATH"
{code}

However, I got the following exception:
{code}

When I ran MR, it worked. Could someone let me know what I did wrong? Thanks.
