Gerson Carlos commented on HDFS-6662:
-------------------------------------
I was able to reproduce the bug on the latest 3.0.0 code from the git repo.
It looks like the uri wasn't being properly encoded before send the request,
i.e., % should be converted to %25. So, I added to explorer.js an encoding
command.
But after that, the datanode broke when answering, because it wasn't decoding
the uris. To fix that, I added to ParameterParser.java the decoding command
from QueryStringDecoder.
See the attached hdfs-6662.patch for the diff code.
