[GitHub] [iotdb] JackieTien97 opened a new pull request #2775: Fix the sketch tool in new tsfile format
JackieTien97 opened a new pull request #2775:
URL: https://github.com/apache/iotdb/pull/2775
## Problems
The tsfile format has been changed, but the tsfile sketch tool is not updated yet. While using the SketchTool to analyze a new format tsfile will throw Exception like the following:
## Reasons
* The new tsfile format has added a new structure called PlanIndex after each chunk group which is used by distributed iotdb, while scanning the tsfile in tsfile sketch tool, we should skip it.
* While reading data from ByteBuffer, I forgot to flip it.
## Solutions
* skip the PlanIndex after each chunk group which occupys 17 bytes
* flip the ByteBuffer.
