org.apache.hadoop.mapred.LocalClientProtocolProvider not found

Question

I wrote a program to execute a embeded Pig sentence in Java. I executed the java sentence registryQuery. But when I try on to store the result, I give a error of org.apache.hadoop.mapred.localClientProtocolProvider not found. I don't understand this error.

Attached are the sentences:

This is the java code

 pigServer.registerQuery("source = load '"+ inputFile + "' USING    org.apache.pig.backend.hadoop.hbase.HBaseStorage( " +
"'datos:bikes', '-loadKey true')"+
"as (id1:int, bikes:int) ;");

Path output = new Path("consulta1");

 pigServer.store("source","consulta1");

This is the java Exception:

What is org.apache.hadoop.mapred.LocalClientProtocolProvider?

Could somebody help me?

Answer 1

It's an old question, but since this could help someone else, I am answering it.

Cause of this problem is that the class

org.apache.hadoop.mapred.LocalClientProtocolProvider

is not found in your class-path. I resolved this error in my setup by adding below maven dependency.

<dependency>
    <groupId>org.apache.hadoop</groupId>
    <artifactId>hadoop-mapreduce-client-common</artifactId>
    <version>2.4.1</version>
</dependency>

As far as the functionality of this class is concerned, I do not have more information as of now, as I myself am learning hadoop and Pig.
