---------------------------------
Summary: Lake checking datatype before writing WAL
Key: IOTDB-264
URL: https://issues.apache.org/jira/browse/IOTDB-264
Project: Apache IoTDB
Issue Type: Bug
Affects Versions: 0.8.0
Reporter: Jialin Qiao
When execute an InsertPlan, we first check whether the timeseries exists or
not. Then we write the InsertPlan to WAL and insert it to memtable. However, if
the data type mismatches the registered schema, WAL will still be written but
inserting to memtable will fail.
When restart IoTDB, the WAL cannot be replayed due to NumberFormatException and
IoTDB will fail to restart.
