Question

我无法使用Hadoop的WebHDFS REST API创建文件。

按照文档，我这样做。

curl -i -X PUT "http://hadoop-primarynamenode:50070/webhdfs/v1/tmp/test1234?op=CREATE&overwrite=false"

响应：

重定向后：

curl -i -X PUT -T MYFILE "http://hadoop-datanode1:50075/webhdfs/v1/tmp/test1234?op=CREATE&namenoderpcaddress=hadoop-primarynamenode:8020"

响应：

HTTP/1.1 400 Bad Request
Content-Type: application/json; charset=utf-8

Connection: close

{"RemoteException":{"exception":"IllegalArgumentException","javaClassName":"java.lang.IllegalArgumentException","message":"Failed to parse \"null\" to Boolean."}}

我找不到该错误消息的任何线索。有没有人经历过这个？

我正在运行使用Ambari安装的Hadoop群集。

似乎第二个PUT命令需要＆＃34; createparent＆＃34;参数。事实上，两者都覆盖了＃34;和＆＃34;创建父母＆＃34;是必要的。 WebHDFS未使用默认值。绝对是一个错误...

curl -i -X PUT -T MYFILE "http://hadoop-datanode1:50075/webhdfs/v1/tmp/test1234?op=CREATE&namenoderpcaddress=hadoop-primarynamenode:8020&overwrite=false&createparent=false"

使用WebHDFS REST API创建文件时出现RemoteException
