             Summary: YARN Web UI have problem when show node partitions 
resource
                 Key: YARN-10660
                 URL: https://issues.apache.org/jira/browse/YARN-10660
             Project: Hadoop YARN
          Issue Type: Bug
          Components: webapp
    Affects Versions: 3.2.1
            Reporter: tuyu
             Fix For: 3.2.1


when enable yarn label function, Yarn UI will show queue resource base on 
partitions,but there have some problem when click expand button. The url will 
increase very long, like  this 

{code:java}
127.0.0.1:20701/cluster/scheduler?openQueues=Partition:%20#Partition:%20#Partition:%20#Partition:%20#Partition:%20#Partition:%20#Partition:%20#Partition:%20#Partition:%20#Partition:%20#Partition:%20#Partition:%20#Partition:%20#Partition:%20#Partition:%20#Partition:%20#Partition:%20#Partition:%20#Partition:%20#Partition:%20#Partition:%20#Partition:%20#Partition:%20#Partition:%20#Partition:%20#Partition:%20#Partition:%20#Partition:%20#Partition:%20#Partition:%20#Partition:%20#Partition:%20#Partition:%20<DEFAULT_PARTITION>%20<memory:491520,%20vCores:96><DEFAULT_PARTITION>%20<memory:491520,%20vCores:96><DEFAULT_PARTITION>%20<memory:491520,%20vCores:96><DEFAULT_PARTITION>%20<memory:491520,%20vCores:96><DEFAULT_PARTITION>%20<memory:491520,%20vCores:96><DEFAULT_PARTITION>%20<memory:491520,%20vCores:96><DEFAULT_PARTITION>%20<memory:491520,%20vCores:96><DEFAULT_PARTITION>%20<memory:491520,%20vCores:96><DEFAULT_PARTITION>%20<memory:491520,%20vCores:96><DEFAULT_PARTITION>%20<memory:491520,%20vCores:96><DEFAULT_PARTITION>%20<memory:491520,%20vCores:96><DEFAULT_PARTITION>%20<memory:491520,%20vCores:96><DEFAULT_PARTITION>%20<memory:491520,%20vCores:96><DEFAULT_PARTITION>%20<memory:491520,%20vCores:96><DEFAULT_PARTITION>%20<memory:491520,%20vCores:96><DEFAULT_PARTITION>%20<memory:491520,%20vCores:96><DEFAULT_PARTITION>%20<memory:491520,%20vCores:96><DEFAULT_PARTITION>%20<memory:491520,%20vCores:96><DEFAULT_PARTITION>%20<memory:491520,%20vCores:96><DEFAULT_PARTITION>%20<memory:491520,%20vCores:96><DEFAULT_PARTITION>%20<memory:491520,%20vCores:96><DEFAULT_PARTITION>%20<memory:491520,%20vCores:96><DEFAULT_PARTITION>%20<memory:491520,%20vCores:96><DEFAULT_PARTITION>%20<memory:491520,%20vCores:96><DEFAULT_PARTITION>%20<memory:491520,%20vCores:96><DEFAULT_PARTITION>%20<memory:491520,%20vCores:96><DEFAULT_PARTITION>%20<memory:491520,%20vCores:96><DEFAULT_PARTITION>%20<memory:491520,%20vCores:96><DEFAULT_PARTITION>%20<memory:491520,%20vCores:96><DEFAULT_PARTITION>%20<memory:491520,%20vCores:96><DEFAULT_PARTITION>%20<memory:491520,%20vCores:96><DEFAULT_PARTITION>%20<memory:491520,%20vCores:96><DEFAULT_PARTITION>%20<memory:491520,%20vCores:96>
{code}


The root cause is

{code:java}
   origin url is:
      Partition: <DEFAULT_PARTITION> <memory:491520, vCores:96>
   htmlencode is:
      Partition: &lt;DEFAULT_PARTITION&gt; &lt;memory:491520, vCores:96&gt;

  SchedulerPageUtil have some javascript code
     storeExpandedQueue
        tmpCurrentParam = tmpCurrentParam.split('&');",


   the  Partition: &lt;DEFAULT_PARTITION&gt; &lt;memory:491520, vCores:96&gt;  
will split and len > 1, the problem logic is here, if click  expand button 
close, the function will clear params, but it the split array is not match 
orgin url 
{code}
when click expand button close, lt;DEFAULT_PARTITION&gt; &lt;memory:491520, 
vCores:96&gt;  will append, if click expand multi times, the length will 
increase too long
