Whenever I execute the PIG Mapreduce which throws me below Exception
java.lang.NoSuchFieldError: defaultReader
at com.jayway.jsonpath.spi.json.JsonSmartJsonProvider.<init>(JsonSmartJsonProvider.java:39)
at com.jayway.jsonpath.internal.DefaultsImpl.jsonProvider(DefaultsImpl.java:21)

at com.jayway.jsonpath.internal.JsonContext.<init>(JsonContext.java:52)
at com.jayway.jsonpath.JsonPath.parse(JsonPath.java:596)
In-order to solve the problem tried below options
Option 1: Tried setting Registering the json-smart2.3.jar & json-path2.3.0.jar But no promising results (As the Jar it was referencing is json-path1.2.jar)
Option 2: Downgrading my module dependencies to json-path1.2.jar No results
Option 3: Using Custom classLoaders tried to load the jar of JSON-path2.3.0 jar it loaded the class went into issues of Org.slf4j binding
There were multiple binding paths identified, But went problems with sun.misc classloader
Failed to instantiate SLF4J LoggerFactory

Can some one suggest me to solve this problem, Can find one stackoverflow link where it was telling about weblogic and not a generalized solution which can be applied on Hadoop2.7 also (JSON Parser -java.lang.NoSuchFieldError: defaultReader)
Provide the custom implementation to load/parse the JSON so that we can avoid using Json-smart-2.x/1.x of Hadoop/lib
public static void changeJsonPathConfig() {
if (!configChanged) {
Configuration.setDefaults(new Configuration.Defaults() {
private final JsonProvider jsonProvider = new GsonJsonProvider(
new GsonBuilder().serializeNulls().create());
private final MappingProvider mappingProvider = new GsonMappingProvider();
@Override
public JsonProvider jsonProvider() {
return jsonProvider;
}
@Override
public MappingProvider mappingProvider() {
return mappingProvider;
}
@Override
public Set<Option> options() {
return EnumSet.noneOf(Option.class);
}
});
configChanged = true;
}
}
