Make it possible to state MIME type for a webhdfs OPEN operation's result
-------------------------------------------------------------------------
Key: HDFS-3272
URL: https://issues.apache.org/jira/browse/HDFS-3272
Project: Hadoop HDFS
Issue Type: Improvement
Affects Versions: 1.0.1
Reporter: Steve Loughran
Priority: Minor
when you do a GET from the browser with webhdfs, you get the file, but it comes
over as a binary as the browser doesn't know what type it is. Having a mime
mapping table and such like would be one solution, but another is simply to add
a {{mime}} query parameter that would provide a string to be reflected back to
the caller as the Content-Type header in the HTTP response.
e.g.
{code}
http://ranier:50070/webhdfs/v1/results/Debounce/part-r-00000.csv?op=open&mime=text/csv
{code}
would generate a 307 redirect to the datanode, with the
{code}
http://dn1:50075/webhdfs/v1/results/Debounce/part-r-00000.csv?op=open&mime=text/csv
{code}
which would then generate the result
{code}
200 OK
Content-Type:text/csv
