When I use OrcRowInputFormat to read multiple orc files, the system throws one NullPointerException .

the code like this

 
{code:java}
StreamExecutionEnvironment environment = StreamExecutionEnvironment.getExecutionEnvironment();
environment.setParallelism(1);
String path = "file://tmp/dir";
String schema = ..... ;
OrcRowInputFormat orcRowInputFormat = new OrcRowInputFormat(
   path,
   schema,
   new org.apache.hadoop.conf.Configuration());
DataStream dataStream  =environment.createInput(orcRowInputFormat);
dataStream.writeAsText("file:///tmp/aaa", FileSystem.WriteMode.OVERWRITE);
environment.execute();
{code}
 

the exception is 

 
{code:java}
