> {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
