问题
As the title goes.My source code is:
package hbase;
import java.io.IOException;
import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.hbase.HBaseConfiguration;
import org.apache.hadoop.hbase.HColumnDescriptor;
import org.apache.hadoop.hbase.HTableDescriptor;
import org.apache.hadoop.hbase.client.HBaseAdmin;
import org.apache.hadoop.hbase.util.Bytes;
public class HbaseExampleClient {
public static void main(String[] args) throws IOException {
Configuration config = HBaseConfiguration.create();
config.set("hbase.zookeeper.quorum", "192.168.10.17");
config.set("hbase.zookeeper.property.clientPort", "2222");
HBaseAdmin admin = new HBaseAdmin(config);//reports an IBM_JAVA NoSuchFieldError
HTableDescriptor htd = new HTableDescriptor("test1111");
HColumnDescriptor hcd = new HColumnDescriptor("data");
htd.addFamily(hcd);
admin.createTable(htd);
byte[] tablename = htd.getName();
HTableDescriptor[] tables = admin.listTables();
if(tables.length!= 1 && Bytes.equals(tablename, tables[0].getName()))
{
throw new IOException("Failed create of table!");
}
admin.close();
}
}
Exception in thread "main" java.lang.NoSuchFieldError: IBM_JAVA

It seems that this error has nothing to do with hbase server because I can use hbase shell properly. But I really don't konw how to fix this problem.Both from my Laptop(windows) Eclipse and a remote desktop(Ubuntu) linux Eclipse reports the same error.
Anyone can help me?
回答1:
I was also facing the same problem but found the solution, This problem occurs due to jar issue since IBM_JAVA is constant
public static final boolean IBM_JAVA = JAVA_VENDOR_NAME.contains("IBM");
and this constant is define in class org.apache.hadoop.util.PlatformName but this package structure and class is define in two jars:
- hadoop-core
- hadoop-auth
but the class present in hadoop-core does not have this constant.
IBM_JAVA
And your application trying to search in hadoop-core jar. So add hadoop-auth jar in your application.
回答2:
I have faced same problem when using earlier versions of jars for hadoop-core and hadoop-auth. Using below version jars resolves my problem.
hadoop-core-1.2.1.jar
hadoop-auth-2.2.0.jar
回答3:
I had such problem, and removed the fs (filesystem) and security from the hadoop-common-X.X.X.jar. Then I added its compatible source code to my java source codes. Besides I removed hadoop-auth. because it was my first test, I removed them to get my code running.
