我已经用nutch和2.3.1配置了apachehadoop2.7.4、hbase 1.2.6和solr6.6.1。我的 mapred-site.xml 在所有节点上

<property>
  <name>mapreduce.jobtracker.address</name>
  <value>master:9001</value>
 </property>

 <property>
   <name>mapreduce.framework.name</name>
   <value>yarn</value>
 </property>

<property>
  <name>mapreduce.task.timeout</name>
  <value>10000</value>
  <description>The number of milliseconds before a task will be
  terminated if it neither reads an input, writes an output, nor
  updates its status string.  A value of 0 disables the timeout.
  </description>
</property>

<property>
  <name>mapreduce.reduce.memory.mb</name>
  <value>2048</value>
  <description>The amount of memory to request from the scheduler for each
  reduce task.
  </description>
</property>

以及 yarn-site.xml 在所有节点上都有以下配置。

<property>
      <name>yarn.resourcemanager.hostname</name>
      <value>master</value>
   </property>

  <property>
      <name>yarn.nodemanager.aux-services</name>
      <value>mapreduce_shuffle</value>
   </property>

  <property>
    <name>yarn.nodemanager.resource.memory-mb</name>
    <value>3072</value>
  </property>

  <property>
    <name>yarn.nodemanager.resource.cpu-vcores</name>
    <value>2</value>
  </property>

<property>
    <name>yarn.scheduler.minimum-allocation-mb</name>
    <value>1024</value>
  </property>

  <property>
    <name>yarn.scheduler.minimum-allocation-vcores</name>
    <value>1</value>
  </property>

所有作业都成功运行，但在solrindex时失败，出现以下异常

问题出在哪里。我已经检查了所有的日志，但没有错误消息一个以上。第二，当我在独立的机器上运行这个作业（伪模式）时，它完成了，没有任何问题。
