描述：使用一个533M大小的mlog文件启动IoTDB server，client查询输入sql查询`show timeseries root`, 等待若干分钟之后，server抛出异常如下： ``` WARN org.apache.thrift.transport.TIOStreamTransport:112 - Error closing output stream. java.net.SocketException: Socket closed at java.net.SocketOutputStream.socketWrite(SocketOutputStream.java:118) ~[na:1.8.0_161] at java.net.SocketOutputStream.write(SocketOutputStream.java:155) ~[na:1.8.0_161] at java.io.BufferedOutputStream.flushBuffer(BufferedOutputStream.java:82) ~[na:1.8.0_161] at java.io.BufferedOutputStream.flush(BufferedOutputStream.java:140) ~[na:1.8.0_161] at java.io.FilterOutputStream.close(FilterOutputStream.java:158)...
已知iotdb的`TSServiceImpl`类`fetchMetadata`函数中**COLUMN**分支的作用是返回一条路径的数据类型查询结果，特别地，给定一条聚合路径会触发PathErrorException，而此处对于PathErrorException目前只 catch 不处理。 考虑jdbc 的 `resultSet = new TsfileQueryResultSet(this, execResp.getColumns(), client, sessionHandle, operationHandle, sql, execResp.getOperationType(), getColumnsType(execResp.getColumns()))`，当sql是聚合查询语句时， `execResp.getColumns()`得到的是聚合路径（例如"max(root.ln.wf01.wt01)")，`getColumnsType(execResp.getColumns()))`就会执行对该聚合路径的数据类型查询请求，这也是上述对于这种PathErrorException不抛出异常的部分原因。 综上所述，现状是既存在对聚合路径的数据类型查询请求，但是却没有对应的实现，对于聚合路径抛出的异常沉默处理。 改进上述问题的可能的两个方向：1）聚合查询语句的`execResp.getColumns()`得到干净的非聚合路径，或者2）`fetchMetadata`函数的**COLUMN**分支扩展实现对聚合路径的数据类型查询。
