lvshuang commented on IOTDB-1135:
---------------------------------
I have debug to org.apache.iotdb.db.metadata.MTree#getCount, found this method
terminal condition is if node is MeasurementMNode, then return 1.
in this report, "tdouble" is MeasurementMNode, trigger terminal condition, not
traverse it's children, so return 1.
I want to solve this bug, please assign to me and anyone could help me?
