無法使用Java命令運行Pig jar

Question

我正在嘗試簡單的豬代碼，但它給了我一些許可。 這是我的示例豬代碼

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");
   }
}

我將我的類路徑設置如下

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

當我使用java命令運行代碼時，它運行正常，但是當創建了我的代碼罐並嘗試運行時，它給了我以下權限錯誤。

 ****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****

-bash: /usr/hdp/2.3.0.0-2557/pig/pig-0.15.0.2.3.0.0-2557-core-h2.jar: Permission denied

我該如何解決？

Answer 1

嘗試以下

1. 代替/usr/hdp/2.3.0.0-2557/hadoop/client/*使用/usr/hdp/2.3.0.0-2557/hadoop/client/*.jar / *。jar（請參閱結尾的.jar。將所有*替換為* 。罐）
2. 代替分號（;），請嘗試使用冒號（：）。 冒號用於在Linux上分隔路徑
3. 如果上述步驟1不起作用，請嘗試將單個JAR放置在路徑中，而不是* .jar
