> 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

> 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.
