ambari安装的hadoop、hive、sqoop ,用sqoop将数据从oracle导出至hive表，报错Permission denied: user=root, access=WRITE, inode="/user":hdfs:hdfs:drwxr-xr-x!

操作系统rhel6.3 64位，在root下用ambari安装的hadoop、hive、sqoop
各版本如下：
hadoop 2.2.0.2.0.6.0-101
hive 0.12.0.2.0.6.1-101
sqoop 1.4.4.2.0.6.1-101
-------------
sqoop import --hive-import --connect jdbc:oracle:thin:@192.168.88.233:1521:ITSPDB2 --username ITSP --password itsp --verbose --m 1 --table HADOOP_TEST

在root下用sqoop将数据从oracle导出至hive表，报错如下：

注：各/home/hadoop/hdfs目录的权限为777， /home/hadoop/hdfs/data 目录权限为750, 各目录属主为root

求解决方案！
