-------------------------------
Summary: Flushed data size inconsistent exception when writing
measurement(same name but different device) with different data type
Key: IOTDB-401
URL: https://issues.apache.org/jira/browse/IOTDB-401
Project: Apache IoTDB
Issue Type: Bug
Reporter: EJTTianyu
Hi,
My current project requires exporting data from Kairosdb as tsfile. I use the
following steps to complete this task.
1. Query and export kairosdb data to csv;
2. Export csv to tsfile.
In the second step, I encountered the following exception:
{code:java}
ERROR org.apache.iotdb.tsfile.write.chunk.ChunkWriterImpl - meet error in
chunkBuffer.writePageHeaderAndDataIntoBuff, ignore this page:
org.apache.iotdb.tsfile.exception.write.PageException: No valid data point in

You can use the following strategy to reproduce this bug.
First create a time series like d0.s0, whose data type is INT64. Write some
data point to the TsfileWriter. Second create a time series like d1.s0, whose
data type is FLOAT. When writing TSRecord to the same tsfile writer, the bug
occurs.
