我正在尝试从.hql文件执行'copyToLocal'，如下所示:
dfs -copyToLocal hdfs://nameservice1/HDFS_FOLDER1/HDFS_FOLDER2/file_name.dat /LOCAL_FOLDER1/LOCAL_FOLDER2/;
但是我得到下面提到的异常:

但是，当我在一段时间后使用相同的.hql文件执行相同的语句时，它会按预期复制到本地。 谁能帮助我了解为什么会这样吗？
Version: Hive 1.1.0-cdh5.8.3
更新1 :我使用“get”而不是“copyToLocal”，并且得到了相同的异常。
更新2 :此文件具有粘性位:
-rwxrwxrwt ..... /HDFS_FOLDER1/HDFS_FOLDER2/file_name.dat
我是创建文件的用户，我正在尝试使用HQL文件中的dfs选项将其从HDFS复制到本地文件夹。
最佳答案
HADOOP命令用于复制到本地文件位置。
hdfs dfs -copyToLocal <input> <output>
这是您的确切示例:
hdfs dfs -copyToLocal /nameservice1/HDFS_FOLDER1/HDFS_FOLDER2/file_name.dat /LOCAL_FOLDER1/LOCAL_FOLDER2;
这是不推荐使用的版本:
hadoop fs -copyToLocal /nameservice1/HDFS_FOLDER1/HDFS_FOLDER2/file_name.dat /LOCAL_FOLDER1/LOCAL_FOLDER2;
HIVE命令，用于将文件复制到本地文件位置。
INSERT OVERWRITE LOCAL DIRECTORY '/your/directory/in/local' SELECT * FROM myTable
关于hadoop - hive :dfs copyToLocal给出 “org.apache.hive.service.cli.HiveSQLException: Error while processing statement: null”，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/41224222/
