---------------------------------
Summary: COUNT NODE can only count when LEVEL is specified at the
last level
Key: IOTDB-2363
URL: https://issues.apache.org/jira/browse/IOTDB-2363
Project: Apache IoTDB
Issue Type: Bug
Components: Core/Engine
Reporter: Tian Jiang

I first created a timeseries "root.sg1.a.b.c.d1.s1", then I executed "count
nodes root.**.c.d1.s1 level=5" and the result was 0. But if I executed "count
nodes root.**.c.d1.s1 level=6", the result was 1.

The reason is that the implementation of MNodeLevelCounter only considers fully
matched paths, so if the given LEVEL does not correspond to the last level of
matched paths, no nodes will be counted.
