我试图实现搜索引擎在hdfs与solr我已经成功地安装了hadoop，但在配置solr得到一些错误。。。我是新来solr的请帮忙
solrconfig.xml文件

<directoryFactory name="DirectoryFactory" class="solr.HdfsDirectoryFactory">
      <str name="solr.hdfs.home">hdfs://127.0.0.1:10001/home/hadoop/hadoop-datastore/tmp/dfs/solr</str>
      <str name="solr.hdfs.confdir">/home/hadoop/hadoop-1.2.1/conf</str>
    <bool name="solr.hdfs.blockcache.enabled">true</bool>
      <int name="solr.hdfs.blockcache.slab.count">1</int>
      <bool name="solr.hdfs.blockcache.direct.memory.allocation">true</bool>
      <int name="solr.hdfs.blockcache.blocksperbank">16384</int>
      <bool name="solr.hdfs.blockcache.read.enabled">true</bool>
      <bool name="solr.hdfs.blockcache.write.enabled">true</bool>
      <bool name="solr.hdfs.nrtcachingdirectory.enable">true</bool>
      <int name="solr.hdfs.nrtcachingdirectory.maxmergesizemb">16</int>
      <int name="solr.hdfs.nrtcachingdirectory.maxcachedmb">192</int>
    </directoryFactory>

请让我知道我在这个文件上犯了什么错误
我正试图开始解决，请让我知道这是正确的或不

java -Dsolr.directoryFactory=HdfsDirectoryFactory -Dsolr.lock.type=hdfs -Dsolr.hdfs.home=hdfs://127.0.0.1:10001/home/hadoop/hadoop-datastore/tmp/dfs/solr -Dsolr.hdfs.confdir=/home/hadoop/hadoop-1.2.1/conf -jar start.jar

启动时出错消息
