how to merge duplicate lead with batch apex based on email ?

global class LeadBatchAviodDuplicacy implements Database.Batchable<sObject> {

public String queryString;

global Database.QueryLocator start(Database.BatchableContext BC) {

queryString = 'SELECT Id, Name, Email FROM Lead ';

return Database.getQueryLocator(queryString);

}

global void execute(Database.BatchableContext BC, List<Lead> obj) {

Map<String,List<Lead>> LeadMap = new Map<String,List<Lead>>();

Set<String> LeadName = new Set<String>();

Set<String> LeadEmail = new Set<String>();

for(Lead a :obj){

LeadName.add(a.Name.toLowerCase());

if(String.isnotblank(a.Email))

LeadEmail.add(a.Email.toLowerCase());

}

//Get All non formula fields of Lead

String sobjectApiName = 'Lead';

Map<String, Schema.SObjectType> schemaMap = Schema.getGlobalDescribe();

Map<String, Schema.SObjectField> fieldMap = schemaMap.get(SobjectApiName).getDescribe().fields.getMap();

List<String> fieleList = new List<String>();

for(String fieldName : fieldMap.keySet()){

Schema.DescribeFieldResult fieldResult = fieldMap.get(fieldName).getDescribe();

if(!fieldResult.isCalculated() && fieldResult.isCreateable() && !fieldResult.isExternalId()&& fieldResult.isUpdateable()){

fieleList.add(fieldName);

}

/*if(fieldName != 'isPartner' && fieldName != 'IsCustomerPortal'){

fieleList.add(fieldName);

}*/

}

String fetchFields = 'SELECT '+String.join(fieleList,',')+' FROM '+sobjectApiName+' WHERE Email IN :LeadEmail';

integer i = 1;

for(Lead a : Database.query(fetchFields)){

String key = a.Email;

key = key.toLowerCase();

if(LeadMap.containsKey(key)){

LeadMap.get(key).add(a);

}else {

LeadMap.put(key,new List<Lead>{a});

}

i++;

}

System.debug('i >'+i);

System.debug('LeadMap >> '+LeadMap);

List<Lead> mergeList;

for(String key : LeadMap.keySet()){

System.debug('Size >>'+ LeadMap.get(key).size());

if(LeadMap.get(key).size()>1 ){

mergeList = new List<Lead>();

Lead masterLead = LeadMap.get(key)[0];

mergeList.addAll(LeadMap.get(key));

mergeList.remove(0);

System.debug('mergeList >> '+mergeList);

for(Lead a : mergeList){

Database.MergeResult mergeResult = Database.merge(masterLead, a, true);

}

}

}

//if(mergeList.size()>0)

// update mergeList;

}

global void finish(Database.BatchableContext BC) {

}

}

I'm unable to map fields and feed fields.
