> Remove hadoop1.x code in HadoopUtils
> ------------------------------------
>
> Key: FLINK-7118
> URL: https://issues.apache.org/jira/browse/FLINK-7118
> Project: Flink
> Issue Type: Improvement
> Components: Java API
> Reporter: mingleizhang
> Assignee: mingleizhang
> Fix For: 1.4.0

>
> Since flink no longer support hadoop 1.x version, we should remove it. Below
> code reside in {{org.apache.flink.api.java.hadoop.mapred.utils.HadoopUtils}}
>
> {code:java}
> public static JobContext instantiateJobContext(Configuration configuration,
> JobID jobId) throws Exception {
> try {
> Class<?> clazz;
> // for Hadoop 1.xx
> if(JobContext.class.isInterface()) {
> clazz =
> Class.forName("org.apache.hadoop.mapreduce.task.JobContextImpl", true,
> Thread.currentThread().getContextClassLoader());
> }
> // for Hadoop 2.xx
> else {
> clazz =
> Class.forName("org.apache.hadoop.mapreduce.JobContext", true,
> Thread.currentThread().getContextClassLoader());
> }
> Constructor<?> constructor =
> clazz.getConstructor(Configuration.class, JobID.class);
> JobContext context = (JobContext)
> constructor.newInstance(configuration, jobId);
>
> return context;
> } catch(Exception e) {
> throw new Exception("Could not create instance of
> JobContext.");
> }
> }
> {code}
> And
> {code:java}
> public static TaskAttemptContext
> instantiateTaskAttemptContext(Configuration configuration, TaskAttemptID
> taskAttemptID) throws Exception {
> try {
> Class<?> clazz;
> // for Hadoop 1.xx
> if(JobContext.class.isInterface()) {
> clazz =
> Class.forName("org.apache.hadoop.mapreduce.task.TaskAttemptContextImpl");
> }
> // for Hadoop 2.xx
> else {
> clazz =
> Class.forName("org.apache.hadoop.mapreduce.TaskAttemptContext");
> }
> Constructor<?> constructor =
> clazz.getConstructor(Configuration.class, TaskAttemptID.class);
> TaskAttemptContext context = (TaskAttemptContext)
> constructor.newInstance(configuration, taskAttemptID);
>
> return context;
> } catch(Exception e) {
> throw new Exception("Could not create instance of
