[jira] [Created] (IOTDB-4633) Unequal value after bytes transformation by BytesUtils in Tsfile

Wendi He created IOTDB-4633:
-------------------------------

             Summary: Unequal value after bytes transformation by BytesUtils in Tsfile
                 Key: IOTDB-4633
                 URL: https://issues.apache.org/jira/browse/IOTDB-4633
             Project: Apache IoTDB
          Issue Type: Bug
          Components: TsFile
            Reporter: Wendi He
         Attachments: example-1-1.jpg, example-1.jpg, example-2.jpg

In iotdb/tsfile, there seems to be some bugs in BytesUtils. BytesUtils.longToBytes is to transform data to bytes and BytesUtils.bytesToLong is to transform the bytes back to the data. The data after transformation is suppoesed to be equal to the data before transformation.

However, in some cases and certain values of data, the value has changed after such transformation. The following examples shows a simple test of this problem.
