hadoop - 由于 HDP 2.5 中的 Solr 异常，Hbase java 代码在表创建时卡住 - SolrServers 可用于处理此请求

Question

我正在尝试使用 java API 将其与 hbase 连接。

我在 192.168.56.101 本地运行 Hortonworks Sandbox(HDP 2.5)。

以下是我的java代码

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 ");
   }
} 

下面是输出

Trying to connect...
HBase is running!

如您所见，它卡住了，“获得的表”没有打印出来。因此没有得到表。

我正在使用以下 jar :
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

更新我还创建了一个可运行的 jar 并尝试直接在集群上运行它。它仍然没有运行。

您的错误与 HDP 2.5 中 HBase 工作所需的 Solr 引擎有关。尝试启动Infra服务和阿特拉斯服务。关注this文章来做到这一点。在此之后，您的 HBase 操作应该可以正常工作。
