John Zhuge updated HDFS-10684:
------------------------------
Labels: newbie (was: )
> WebHDFS calls fail when boolean parameters not provided
> -------------------------------------------------------
>
> Key: HDFS-10684
> URL: https://issues.apache.org/jira/browse/HDFS-10684
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: webhdfs
> Affects Versions: 2.7.1
> Reporter: Samuel Low
> Labels: newbie
>
> Optional boolean parameters that are not provided in the URL cause the
> WebHDFS create file command to fail.
> curl -i -X PUT
> "http://hadoop-primarynamenode:50070/webhdfs/v1/tmp/test1234?op=CREATE&overwrite=false";
> Response:
> HTTP/1.1 307 TEMPORARY_REDIRECT
> Cache-Control: no-cache
> Expires: Fri, 15 Jul 2016 04:10:13 GMT
> Date: Fri, 15 Jul 2016 04:10:13 GMT

> Content-Length: 0
> Server: Jetty(6.1.26)
> Following the redirect:
> curl -i -X PUT -T MYFILE
> "http://hadoop-datanode1:50075/webhdfs/v1/tmp/test1234?op=CREATE&namenoderpcaddress=hadoop-primarynamenode:8020";
> Response:
> HTTP/1.1 100 Continue
> HTTP/1.1 400 Bad Request
> Content-Type: application/json; charset=utf-8
> Content-Length: 162
> Connection: close
>
> {"RemoteException":{"exception":"IllegalArgumentException","javaClassName":"java.lang.IllegalArgumentException","message":"Failed
> to parse \"null\" to Boolean."}}
> The problem can be circumvented by providing both "createparent" and
> "overwrite" parameters.
> However, this is not possible when I have no control over the WebHDFS calls,
> e.g. Ambari and Hue have errors due to this.
