我正在尝试使用myjar.jar作为配置单元中的udf函数，如下所示，

echo "Add myjar.jar"
$HIVE_HOME/bin/hive -e "ADD JAR  /gpfs/user/username/HIVE/myjar.jar;"

echo "List myjar.jar, this is showing local directory path"
$HIVE_HOME/bin/hive -e "list jar;"

$HIVE_HOME/bin/hive -e "drop function if exists myfunction;"

echo "Create temporary function, my class name is UpperCase"

$HIVE_HOME/bin/hive -e "CREATE TEMPORARY FUNCTION myfunction AS 'Upper.UpperCase';"

$HIVE_HOME/bin/hive -e "SELECT myfunction(line) FROM doc where line='COCO';"

但我犯了以下错误，

FAILED: Class Upper.UpperCase not found
FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.FunctionTask

我怀疑问题可能是我的jar没有复制到本地节点目录。但我不确定。
