Summary: [UNLOAD] Make RestorableTsFileWriter have idempotence
Key: IOTDB-2448
URL: https://issues.apache.org/jira/browse/IOTDB-2448
Project: Apache IoTDB
Issue Type: Improvement
Components: Core/TsFile
Reporter: FengQingxin
When we construct a RestorableTsFileWriter on a non-complete TsFile, the write
will truncate the broken ChunkGroup.
However, a ChunkGroup is being seen as complete only we see the next
ChunkGroupHeader.
This causes when new RestorableTsFileWriter twice on a file, it will do
truncate twice, even if the file has a complete ChunkGroup.
We need to identify the end to a ChunkGroup and make sure the
RestorableTsFileWriter will only truncate one time for a TsFile.
