> Key: IOTDB-266
> URL: https://issues.apache.org/jira/browse/IOTDB-266
> Project: Apache IoTDB
> Issue Type: Bug
> Reporter: Xiangdong Huang
> Priority: Major
> Labels: pull-request-available
> Fix For: 0.9.0
>
> Time Spent: 20m
> Remaining Estimate: 0h
>
> The code is:
> {code:java}
> //代码占位符
> ReadOnlyTsFile tsFileReader = new ReadOnlyTsFile(new
> TsFileSequenceReader("file.tsfile"));
> ArrayList<Path> paths = new ArrayList<>();
> paths.add(new Path("system.test_cpu"));
> // no filter, should select 1 2 3 4 6 7 8
> queryAndPrint(paths, tsFileReader, null);
> tsFileReader.close();
> {code}
> , and actually the correct path is "root.app.system.test_cpu". Now because I
> define an incorrect path (i.e., not exist in the tsfile), then I get an
> exception:
