Subject [jira] [Updated] (HDFS-10684) WebHDFS calls fail when boolean parameters not provided
Date Mon, 25 Jul 2016 07:23:20 GMT

     [ https://issues.apache.org/jira/browse/HDFS-10684?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Samuel Low updated HDFS-10684:
------------------------------
    Description: 
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
    Pragma: no-cache
    Expires: Fri, 15 Jul 2016 04:10:13 GMT
    Date: Fri, 15 Jul 2016 04:10:13 GMT
    Pragma: no-cache
    Content-Type: application/octet-stream
    Location: http://hadoop-datanode1:50075/webhdfs/v1/tmp/test1234?op=CREATE&namenoderpcaddress=hadoop-primarynamenode:8020&overwrite=false
    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&overwrite=false"

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.
