Hbase 与 Zookeeper 的连接频繁连接和断开连接，但代码以 0 退出

Question

我正在使用 TitanDB，存储后端 Hbase 由 zookeeper 和索引后端管理:Elasticsearch我的问题是 hbase 与 zookeeper 连接并立即断开连接，但代码以 0 退出。

==================elasticsearch.yml=====

cluster.name: elasticsearch_graph_dev
script.disable_dynamic: true
node.name: "node_graph_dev"
bootstrap.mlockall: true
network.host: 127.0.0.1

==================hbase-site.xml========

<configuration>
<property>
    <name>hbase.zookeeper.property.dataDir</name>
    <value>/zookeeper</value>
</property>
<property>
    <name>zookeeper.znode.parent</name>
    <value>/hbase-unsecure</value>

    <value>true</value>
</property>
<property>
    <name>hbase.cluster.distributed</name>
    <value>true</value>
</property>

</configuration>

==============zoo.cfg========

enter code here

tickTime=2000
initLimit=10
syncLimit=5
dataDir=/tmp/zookeeper
clientPort=2181

Titan version = 1.0.0
hbase version = 0.98.12
zookeeper version = 3.4.6
elasticsearch version = 1.5.1

============================================= =======

上面的信息一直打印很多次，我想知道打印多次好还是只打印一次好(然后怎么解决)。

我可以看到我在 elasticsearch gui 中创建的索引以及 hbase 终端 + gui 中的表。

谢谢

如前所述here ，这些都只是 INFO 消息。这只是噪音。如果它们打扰您，您可以使用 log4j 属性配置日志记录级别以减少它们。

log4j.logger.org.apache.zookeeper=WARN
log4j.logger.org.apache.hadoop.hbase.client=WARN
log4j.logger.org.apache.hadoop.hbase.zookeeper=WARN
