将Solr指标推送到Ganglia时出错

Question

我是Solr的新手，并试图将solr指标推向Ganglia。我修改了solr.xml如下：

<solr>

  <solrcloud>

    <str name="host">${host:}</str>
    <int name="hostPort">${jetty.port:8983}</int>
    <str name="hostContext">${hostContext:solr}</str>

    <bool name="genericCoreNodeNames">${genericCoreNodeNames:true}</bool>

    <int name="zkClientTimeout">${zkClientTimeout:30000}</int>
    <int name="distribUpdateSoTimeout">${distribUpdateSoTimeout:600000}</int>
    <int name="distribUpdateConnTimeout">${distribUpdateConnTimeout:60000}</int>
    <str name="zkCredentialsProvider">${zkCredentialsProvider:org.apache.solr.common.cloud.DefaultZkCredentialsProvider}</str>
    <str name="zkACLProvider">${zkACLProvider:org.apache.solr.common.cloud.DefaultZkACLProvider}</str>

  </solrcloud>

  <shardHandlerFactory name="shardHandlerFactory"
    class="HttpShardHandlerFactory">
    <int name="socketTimeout">${socketTimeout:600000}</int>
    <int name="connTimeout">${connTimeout:60000}</int>
  </shardHandlerFactory>
<metrics>
  <reporter name="ganglia" group="node, jvm" class="org.apache.solr.metrics.reporters.SolrGangliaReporter">
    <str name="host">Ganglia IP</str>
    <int name="port">8649</int>
    <int name="period">60</int>
    <str name="prefix">solr</str>
  </reporter>
</metrics>

</solr>

现在我正在尝试重启Solr服务它sis抛出以下错误：

Solr版本：6.6操作系统：Ubuntu 16.04

我花了相当多的时间在谷歌搜索这个错误，但没有得到它的解决方案
