运行程序时，运行到这个方法报下面的错误，请大神们帮忙解决一下

ERROR: JDWP Unable to get JNI 1.2 environment, jvm->GetEnv() return code = -2

就是这段程序
String sPath = "hdfs://ip:9000/09/11111111111.seq";
Configuration cfg = new Configuration();
FileSystem fs = FileSystem.get(URI.create(sPath), cfg);//在这个地方出的错
Path path = new Path(sPath);
SequenceFile.Reader reader = new SequenceFile.Reader(fs,
path, cfg);

最佳答案
