I am trying to simple pig code but its giving me some permission. Here is my sample pig code
import java.io.IOException;
import org.apache.pig.PigServer;
import org.apache.pig.ExecType;
import org.apache.hadoop.conf.Configuration;
public class PigTest{
public static void main(String[] args) {
try {
Configuration conf = new Configuration();
conf.set("hdp.version","2.3.0.0-2557");
//PigServer pigServer = new PigServer("mapreduce",conf);
PigServer pigServer = new PigServer(ExecType.MAPREDUCE, conf);
runIdQuery(pigServer, "myfile.txt");
}
catch(Exception e) {
}
}
public static void runIdQuery(PigServer pigServer, String inputFile) throws IOException {
pigServer.registerQuery("A = load '" + inputFile + "' using PigStorage(':');");
pigServer.registerQuery("B = foreach A generate $0 as id;");
pigServer.store("B", "idout");
}
}
I set my classpath as below
echo $CLASSPATH
.:/usr/hdp/2.3.0.0-2557/hadoop/client/*:/usr/hdp/2.3.0.0-2557/hadoop-hdfs/lib/*:/usr/hdp/2.3.0.0-2557/hadoop-mapreduce/lib/*:/usr/hdp/2.3.0.0-2557/hadoop-yarn/lib/*:/usr/hdp/2.3.0.0-2557/pig/lib/*:/usr/hdp/2.3.0.0-2557/hadoop/conf:/usr/hdp/2.3.0.0-2557/pig/pig-0.15.0.2.3.0.0-2557-core-h2.jar
When i am running my code with java command it is working perfectly but when created a jar of my code and trying to run , it is giving me below permission error.
****java -cp /usr/hdp/2.3.0.0-2557/hadoop/client/*;/usr/hdp/2.3.0.0-2557/hadoop-hdfs/lib/*;/usr/hdp/2.3.0.0-2557/hadoop-mapreduce/lib/*;/usr/hdp/2.3.0.0-2557/hadoop-yarn/lib/*;/usr/hdp/2.3.0.0-2557/pig/lib/*;/usr/hdp/2.3.0.0-2557/hadoop/conf;/usr/hdp/2.3.0.0-2557/pig/pig-0.15.0.2.3.0.0-2557-core-h2.jar -jar PigTest.jar****

How do i fix this?
Try the following
/usr/hdp/2.3.0.0-2557/hadoop/client/*
use /usr/hdp/2.3.0.0-2557/hadoop/client/*.jar
(See .jar at the end. Replace all * with *.jar)
