---------------------------------
Summary: 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
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

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.
