未找到org.apache.hadoop.mapred.LocalClientProtocolProvider

我编写了一个用Java执行嵌入式猪句的程序.我执行了java语句registryQuery.但是当我尝试存储结果时,我发现了找不到org.apache.hadoop.mapred.localClientProtocolProvider的错误.我不明白这个错误.

附上句子:

这是java代码

 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");

这是java异常:

什么是org.apache.hadoop.mapred.LocalClientProtocolProvider？

有人能帮帮我吗？
