Jing Wang created HDFS-14423:
--------------------------------

             Summary: Percent (%) characters no longer work in WebHDFS
                 Key: HDFS-14423
                 URL: https://issues.apache.org/jira/browse/HDFS-14423
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: webhdfs
    Affects Versions: 3.1.2, 3.2.0
         Environment: Ubuntu 16.04, but I believe this is irrelevant.
            Reporter: Jing Wang


The following commands no longer work starting with version 3.1:

{code}
$ hadoop/bin/hdfs dfs -touchz webhdfs://localhost/%
$ hadoop/bin/hdfs dfs -cat webhdfs://localhost/%
cat: URLDecoder: Incomplete trailing escape (%) pattern
{code}

I can confirm that they work correctly on 2.9 and 3.0. Also, the usual hdfs:// 
client works as expected.

I suspect a relation with HDFS-13176 or HDFS-13582, but I'm not sure what the 
right fix is. Note that Hive uses % to escape special characters in partition 
values, so banning % might not be a good option. For example, Hive will create 
a paths like {{table_name/partition_key=%2F}} when {{partition_key='/'}}.
