      Work Description: Flamingo93 opened a new pull request, #638:
URL: https://github.com/apache/knox/pull/638

   ## What changes were proposed in this pull request?
   @risdenk use `org.apache.knox.gateway.dispatch.URLDecodingDispatch` for 
HDFSUI dispatch ha-class  in https://github.com/apache/knox/pull/103. But 
`URLDecodingDispatch` didn't do failover request when request failed. 
   
   I recommend using `org.apache.knox.gateway.hdfs.dispatch.HdfsUIHaDispatch` 
for this, but it  it lack URL decoding what  `URLDecodingDispatch` do. So I 
override `getDispatchUrl` method in `HdfsUIHaDispatch`, decode url just like 
`URLDecodingDispatch`.
   
   ## How was this patch tested?
   
   - mvn clean verify -Ppackage,release
   - Checked that HDFSUI service definition works with HaProvider on cluster
