java hdfs api protocol buffer exception

Question

I'm running a java app using hadoop-2.0.5-alpha. My code looks like:

FileSystem fileSystem = FileSystem.get(conf);
Path path = new Path("/tmp/sample.txt");
System.out.println(fileSystem.exists(path));

But I get an exception

com.google.protobuf.InvalidProtocolBufferException: Message missing required fields: callId, status

I haven't been able to find much on what causes this error. Any thoughts?

Can you provide your environment? What's your HDFS version? It seems you are using hadoop-2.0.5-alpha in the client. But the sever version may be too slow. Type hadoop version to check the version. — zsxwing

Ah yes, you may be correct here. Let me try changing the version and I'll post back shortly. — Jeff Storey

I had the same issue (Hadoop server 2.10 in Docker, Spark 2.3.2+hadoop-client 2.6.5). It magically disappeared after recreating Hadoop container from scratch. — Winand
