I am trying to Access HDFS from Java (Eclipse), to check whether a file exists. But I am getting an Exception .I am using Hadoop 2.4.0.
Exception : Caused by: com.google.protobuf.InvalidProtocolBufferException: Message missing required fields: callId, status
(This is the code)
Configuration conf = new Configuration();
conf.set(“fs.defaultFS”, “hdfs://localhost:5070″);
conf.set(“mapreduce.jobtracker.address”, “hdfs://quickstart.cloudera:8032″);
conf.set(“yarn.resourcemanager.address”, “hdfs://quickstart.cloudera:8032″);
FileSystem fs = FileSystem.get(conf); // Setting up the required configurations
Path p4 = new Path(“/user/hdpuser/input/data/a.txt”);
if(fs.exists(p4))
{
System.out.println(“File Exists”);
}
