JSON Path 2.3.0 conflicts with hadoop 2.7 Environment JSON-smart1.2.0.jar

Question

Have a Input of JSON inside HDFS location
It is required to parse the JSON and to aggregate results
To do am using the PIG UDF which are using JSON-path libraries
On the hadoop2.7 environment jar: json-smart1.2, json-path1.2 are hardbinded

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.Configuration.defaultConfiguration(Configuration.java:174)
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

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)

Any luck with the solution? I am also facing the same issue!!! — Sandeep Shetty, Apr 22 '20 at 11:29
@SyedMazreena : Does all the properties for Jsonpath is available in the one which you had mentioned ? — Sam Berchmans, Aug 04 '20 at 16:14
@SyedMazreena - I am currently using Hadoop 2.6 Is there by any chance the issue is fixed in higher version of Hadoop ? — Sam Berchmans, Aug 04 '20 at 17:04
@SandeepShetty - Please do let me know if you are able to fix this issue. — Sam Berchmans, Aug 04 '20 at 17:04

As hadoop environment(Pig, hdfs, Hive & etc) is using json-path-2.3.0, Its better user Mapper logic should use another version "jsonpath-1.0.jar" will solve the problem

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;

    }

}

Above seems to be perfect solution for this – Syed Rafi Sep 23 '20 at 06:52 — Syed Rafi, Sep 23 '20 at 06:52
