由於HDP 2.5中的Solr異常，Hbase java代碼陷入了Table Creation - SolrServers可用於處理此請求

Question

我正在嘗試使用java API將其與hbase連接。

我在192.168.56.101本地運行Hortonworks Sandbox（HDP 2.5）。

以下是我的java代碼

import java.io.IOException;

import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.hbase.HBaseConfiguration;
import org.apache.hadoop.hbase.client.HTable;
import org.apache.hadoop.hbase.client.Put;
import org.apache.hadoop.hbase.util.Bytes;

public class InsertData{

   public static void main(String[] args) throws IOException {

      // Instantiating Configuration class
       System.out.println("Trying to connect...");

       Configuration configuration = HBaseConfiguration.create();
       configuration.set("hbase.zookeeper.property.clientPort", "2181");
       configuration.set("hbase.zookeeper.quorum", "192.168.56.101");
       configuration.set("zookeeper.znode.parent", "/hbase-unsecure");

       System.out.println("HBase is running!");

       // creating a new table
       HTable table = new HTable(configuration, "emp");
       System.out.println("Table obtained ");
   }
} 

以下是輸出

Trying to connect...
HBase is running!

正如你所看到它被卡住了，“獲得的桌子”沒有被打印出來。 因此沒有獲得表格。

我正在使用以下罐子：
1）commons-configuration-1.8.jar
2）commons-lang-2.6.jar
3）commons-logging-1.1.1.jar
4）hadoop-core-1.0.0.jar
5）hbase-0.92.1.jar
6）log4j-1.2.16.jar
7）slf4j-api-1.5.8.jar
8）slf4j-log4j12-1.5.8.jar
9）zookeeper-3.4.3.jar

更新我還創建了一個可運行的jar並嘗試直接在集群上運行它。 它還沒有運行。

您的錯誤與在HDP 2.5中HBase工作所需的Solr引擎有關。 嘗試啟動Infra服務和Atlas服務。 請按照這篇文章執行此操作。 在此之后你的HBase操作應該工作。
