> 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 this page
> 	at org.apache.iotdb.tsfile.write.chunk.ChunkBuffer.writePageHeaderAndDataIntoBuff(ChunkBuffer.java:91)

> 	at org.apache.iotdb.tsfile.write.TsFileWriter.close(TsFileWriter.java:337)
> ERROR kairosdb.export.csv.TransToTsfile - error occurs when generate tsfile
> java.io.IOException: Flushed data size is inconsistent with computation! Estimated: 29, Actual: 0
> 	at org.apache.iotdb.tsfile.write.TsFileWriter.flushAllChunkGroups(TsFileWriter.java:312)
> 	at org.apache.iotdb.tsfile.write.TsFileWriter.close(TsFileWriter.java:337)
> {code}
> 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.
