java – 使用HBql Zookeeper不会尝试使用SASL进行身份验证

2019-07-04 04:39:50 作者：互联网

我想测试HBql以简单使用HBase.我按照HBql网站(http://www.hbql.com/installation.html)中描述的步骤进行测试.最后在HBql-console中键入version-command以验证我的安装时,我收到以下消息：

这些消息仅在使用HBql控制台时打印. HBase在分布式模式下成功运行,在Debian squeeze上将数据存储在HDFS中.您需要更多信息吗？我犯了什么错误？为什么需要SASL,一般情况下不像HBase shell？

也许一些重要的配置：

hbase-env.sh

hbase_manage_zk=true

HBase的-site.xml中

    <property>
      <name>hbase.zookeeper.property.clientPort</name>
      <value>2222</value>
    </property>
    <property>
      <name>hbase.zookeeper.quorum</name>
      <value>master</value>
    </property>
    <property>
      <name>hbase.zookeeper.property.dataDir</name>
      <value>/usr/local/zookeeper</value>
    </property>

谢谢！

解决方法:

我最近用Nutch和Solr安装了HBase,并遇到了类似的问题.我不确定是否完全相同,不幸的是我没有日志,但它肯定是连接相关的.

事实证明,ZooKeeper的默认连接限制太低,并且在hbase-site.xml中增加此值为我解决了这个问题：

<property>
    <name>hbase.zookeeper.property.maxClientCnxns</name>
    <value>1000</value>
</property>
