----------------------------------
Summary: Count timeserise column name is wrong
Key: IOTDB-1050
URL: https://issues.apache.org/jira/browse/IOTDB-1050
Project: Apache IoTDB
Issue Type: Bug
Reporter: Kaifeng Xue
In master, when using session iterator to run:
```
SessionDataSet sessionDataSet = session.executeQueryStatement("COUNT TIMESERIES
root.sg1.d1");
sessionDataSet.setFetchSize(1024);
DataIterator iterator = sessionDataSet.iterator();
int count = 0;
while (iterator.next()) {
System.out.println(iterator.getString("count"));
count++;
}
```
You will get a NPE because the column name in iterator's columnOrdinalMap is
called "child path" rather than "count"
