《IOTDB用户手册- 0.12-snapshot-20210305.pdf》 P115  7.6.2.4 读取现有 TsFile 示例 
 

/**
 * The class is to show how to read TsFile file named "test.tsfile". The TsFile file "test.tsfile"
 * is generated from class TsFileWriteWithTSRecord or TsFileWriteWithTablet. Run
 * TsFileWriteWithTSRecord or TsFileWriteWithTablet to generate the test.tsfile first
 */

 

Run this class，got the exception：

Exception in thread "main" java.lang.NullPointerException
 at java.util.TreeMap.getEntry(TreeMap.java:347)
 at java.util.TreeMap.containsKey(TreeMap.java:232)

Change 

"paths.add(new Path("device_1.sensor_1"));"

into 

"paths.add(new Path("device_1", "sensor_1"));"

 

the result set is right.
