陷阱Spring上下文关闭错误

我有一个使用spring-hadoop的spring集成项目.
我有一个如下的Hbase模板,

<beans:bean id="fsh" class="org.springframework.data.hadoop.fs.FsShell">
</beans:bean>

<beans:bean id="hbaseTemplate"  
   class="org.springframework.data.hadoop.hbase.HbaseTemplate">
    <beans:property name="configuration" ref="hdpConfiguration" />
</beans:bean>

现在,当我关闭应用程序和上下文时,它会引发一个奇怪的错误,

o.a.h.hbase.client.HConnectionManager : Connection not found in the list, can’t delete it (connection key=HConnectionKey{properties={hbase.zookeeper.quorum=xxx.com,xxx.com, hbase.rpc.timeout=60000, hbase.client.prefetch.limit=10, hbase.zookeeper.property.clientPort=2181, zookeeper.znode.parent=/hbase-secure, hbase.client.retries.number=35, hbase.client.pause=100}, username=’[email protected]’}). May be the key was modified?

据我了解,这是一个无害的错误,甚至在Hadoop 1.x中也被抛出.

我已经迁移到Hadoop 2.x和Spring-Hadoop-2.0.4
但是现在,spring抛出了一个异常,该异常以前没有被抛出,

问题,如何捕获此错误,以便不向用户显示该错误…

感谢您的见解.

解决方法:

只需将delete-connection设置为false,即可解决错误(默认值为“ true”)

<hbase-configuration configration-ref="hdpConfiguration" delete-connection="false"/>
