在 internalRead 中累积 IOExceptions

Question

我正在尝试使用 geomesa 查询累积 table，一切正常很好，我得到了正确的查询结果，但收到了警告记录了大约 "Error closing output stream"。这是示例日志：

[WARN]  2017-05-04 13:00:00 TIOStreamTransport:112 - Error closing output stream.

    at java.lang.Thread.run(Thread.java:745)

我也在 accumulo 网络界面上获取日志：

at org.apache.thrift.server.TNonblockingServer$SelectAcceptThread.run(TNonblockingServer.java:154)

我搜索了相同的内容，但发现它在说些什么与使集群过载有关（我认为不会发生）。如何解决？

欢迎任何帮助和建议。

在 jira 上发现了一个未解决的错误 refer this 对于临时解决方法，我们可以通过在 accumulo

的 conf/generic_logger.xml 中添加以下记录器标记来禁用此警告

<logger name="org.apache.accumulo.server.util.TServerUtils$THsHaServer">
  <level value="ERROR"/>
</logger>
