导入外部TSFILE 问题 (bug when loading a manually generated TsFile into IoTDB instance) #1551
Description
通过example建立的tsfile文件
在导入的时候提示 411
如下
IoTDB> load "D:\iotDb\testTsFile\1595501732489-1-0.tsfile"
Msg: 411: Cannot load file D:\iotDb\testTsFile\1595501732489-1-0.tsfile because null
但是查询此组，还可以能查询到数据
生成tsfile的Example里面不知道是不是有bug

原版代码如下
List measurementSchemas = new ArrayList<>();
// add measurements into file schema (all with INT64 data type)
for (int i = 0; i < sensorNum; i++) {
measurementSchemas.add(
new MeasurementSchema("sensor_" + (i + 1), TSDataType.INT64, TSEncoding.TS_2DIFF));
}
// add measurements into TSFileWriter
try (TsFileWriter tsFileWriter = new TsFileWriter(f, schema)) {
// construct the tablet
Tablet tablet = new Tablet("device_1", measurementSchemas);
我修改成
List measurementSchemas = new ArrayList<>();
// add measurements into file schema (all with INT64 data type)
for (int i = 0; i < sensorNum; i++) {
MeasurementSchema measurementSchema = new MeasurementSchema("sensor_" + (i + 1), TSDataType.INT64, TSEncoding.TS_2DIFF);
measurementSchemas.add(measurementSchema);
schema.registerTimeseries(new Path("root.device_1", measurementSchema.getMeasurementId()), measurementSchema);
}
// add measurements into TSFileWriter
try (TsFileWriter tsFileWriter = new TsFileWriter(f, schema)) {
// construct the tablet
Tablet tablet = new Tablet("root.device_1", measurementSchemas);
可以执行了
而且example生成的tsfile不能直接导入到IOTDB里面，需要将
device_1 替换成 root.device_1才可以
