Accumulo IOExceptions in internalRead


I am trying to query an accumulo table using geomesa, everything works fine, I get the correct result of the query but getting warnings logged about "Error closing output stream". Here is sample log:

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

I am also getting logs on accumulo web interface:

I searched regarding the same but found that it's saying something related to overloading your clusters(which I don't think so happening). How to solve this?

Any help and suggestions are welcomed.


Solution

  • Found an open bug for it on jira refer this For temporary workaround, we can disable this warning by adding the following logger tag in conf/generic_logger.xml of accumulo

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