Description

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

The root cause is

   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 

when click expand button close, lt;DEFAULT_PARTITION> <memory:491520, vCores:96> will append, if click expand multi times, the length will increase too long
