Eric Payne updated HADOOP-11012:
--------------------------------
Attachment: HDFS-6915.201408282053.txt
[~daryn], thank you for reviewing this patch. using {{fsshell.run}} might not
be simple since that would entail creating a new output stream, setting the
{{out}} instance variable for {{Display.Text}}, and then reading from that
stream.
However, with this patch, I was able to anonymously extend the {{Display.Text}}
class and override the {{getInputStream}} method to be public, and then call
{{getInputStream}} directly. Please let me know what you think.
