I'm simply struggling with knowing how to pass the password to authenticate. Any suggestions?</P> Fri, 12 Feb 2016 07:34:28 GMT kvasko 2016-02-12T07:34:28Z https://community.cloudera.com/t5/Archives-of-Support-Questions/Using-C-to-upload-files-via-Knox-LDAP-and-webHDFS/m-p/138308#M19235 <P>I am having trouble finding any documentation on being able to access webHDFS from a C# app (not much of a surprise).

You can use C# classes like WebRequest and NetworkCredentials, here is one good looking <A href="http://stackoverflow.com/questions/1127223/c-sharp-ssl-basic-access-authentication">sample</A>. Try first to list a directory (GET). And note that file upload is a <A href="https://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-hdfs/WebHDFS.html#Create_and_Write_to_a_File">2-step PUT process</A>. </P> Fri, 12 Feb 2016 13:10:49 GMT https://community.cloudera.com/t5/Archives-of-Support-Questions/Using-C-to-upload-files-via-Knox-LDAP-and-webHDFS/m-p/138309#M19236 pminovic 2016-02-12T13:10:49Z
