hive更换tez引擎报错Expected authority at index 7: file://

首先查看hive-env.sh是否是下面形式

 # Set HADOOP_HOME to point to a specific hadoop install directory
export HADOOP_HOME=/opt/SoftWare/Hadoop/hadoop-3.1.3
export HIVE_CONF_DIR=/opt/SoftWare/Hive/hive-3.1.2/conf
  # Folder containing extra libraries required for hive compilation/execution can be controlled by:
export TEZ_HOME=/opt/SoftWare/Hive/hive-3.1.2/tez-0.10.1  
export TEZ_JARS=""
  for jar in `ls $TEZ_HOME |grep jar`; 
  do    export TEZ_JARS=$TEZ_JARS:$TEZ_HOME/$jar
  done
  for jar in `ls $TEZ_HOME/lib`; 
  do    export TEZ_JARS=$TEZ_JARS:$TEZ_HOME/lib/$jar
  done
  export HIVE_AUX_JARS_PATH=$TEZ_JARS

此时TEZ_JARS拼接出的字符串第一个字符是：
而TEZ_JARS的格式应该是文件路径，以逗号分隔

调整为下面形式

export HADOOP_HOME=/opt/SoftWare/Hadoop/hadoop-3.1.3
export HIVE_CONF_DIR=/opt/SoftWare/Hive/hive-3.1.2/conf
export TEZ_HOME=/opt/SoftWare/Hive/hive-3.1.2/tez-0.10.1
export TEZ_JARS=""
for jar in `ls $TEZ_HOME |grep jar`; do
    export TEZ_JARS=$TEZ_JARS,$TEZ_HOME/$jar
done
for jar in `ls $TEZ_HOME/lib`; do
    export TEZ_JARS=$TEZ_JARS,$TEZ_HOME/lib/$jar
done

export HIVE_AUX_JARS_PATH=${TEZ_JARS:1}
echo $HIVE_AUX_JARS_PATH

可以查看到格式就没问题了，后面的操作也可以正常了。
