PIG：python udf流错误

Question

从猪身上调用python udf。我得到以下错误（尝试日志）＆amp;在控制台中获取下面提到的错误。由于相同的代码工作较早，无法跟踪我在哪里做错了。在64位机器上使用RHEL（6.4）和2.7.2 hadoop＆amp; 0.15版猪和＆amp; python 3.5

 Bundle b=new Bundle();
 if(b!=null){
     String imagepath=b.getString("filepath");
 }
 Bitmap myBitmap = BitmapFactory.decodeFile(filepath.get(position));
 imageview.setImageBitmap(myBitmap);      

以下是控制台的错误：

Traceback (most recent call last): File "/tmp/controller2772959444531928936.py", line 356, in <module> sys.argv[5], sys.argv[6], sys.argv[7], sys.argv[8]) File "/tmp/controller2772959444531928936.py", line 88, in main input_str = self.get_next_input() File "/tmp/controller2772959444531928936.py", line 164, in get_next_input while input_str.endswith(END_RECORD_DELIM) == False: TypeError: endswith first arg must be bytes or a tuple of bytes, not str

还有以下错误：

java.lang.Exception: org.apache.pig.impl.streaming.StreamingUDFException: LINE : at org.apache.hadoop.mapred.LocalJobRunner$Job.runTasks(LocalJobRunner.java:462) at org.apache.hadoop.mapred.LocalJobRunner$Job.run(LocalJobRunner.java:522) Caused by: org.apache.pig.impl.streaming.StreamingUDFException: LINE : at org.apache.pig.impl.builtin.StreamingUDF$ProcessErrorThread.run(StreamingUDF.java:503)

以下是python代码：

Exception in thread "Thread-35" java.lang.NullPointerException at org.apache.pig.impl.builtin.StreamingUDF$ProcessOutputThread.run(StreamingUDF.java:468)

以下是猪脚本
