Question

当我尝试连接hive表时，我遇到了错误通过火花

中的HbaseIntegration创建

我遵循的步骤： Hive表创建代码 ：

CREATE TABLE test.sample(id string,name string) 
STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler' WITH     
SERDEPROPERTIES ("hbase.columns.mapping" = ":key,details:name")
TBLPROPERTIES ("hbase.table.name" = "sample");

DESCRIBE TEST;

 col_name data_type comment
 id string from deserializer
 name string from deserializer

使用以下命令启动Spark shell：

spark-shell --master local[2] --driver-class-path /usr/local/hive/lib/hive-   
hbase-handler-1.2.1.jar:
/usr/local/hbase/lib/hbase-server-0.98.9-  
hadoop2.jar:/usr/local/hbase/lib/hbase-protocol-0.98.9-hadoo2.jar:
/usr/local/hbase/lib/hbase-hadoop2-compat-0.98.9-  
hadoop2.jar:/usr/local/hbase/lib/hbase-hadoop-compat-0.98.9-hadoop2.jar:
/usr/local/hbase/lib/hbase-client-0.98.9-   
hadoop2.jar:/usr/local/hbase/lib/hbase-common-0.98.9-hadoop2.jar:
/usr/local/hbase/lib/htrace-core-2.04.jar:/usr/local/hbase/lib/hbase-common-  
0.98.9-hadoop2-tests.jar:
/usr/local/hbase/lib/hbase-server-0.98.9-hadoop2-  
tests.jar:/usr/local/hive/lib/zookeeper-3.4.6.jar:/usr/local/hive/lib/guava-  
14.0.1.jar

在spark-shell中：

val sqlContext=new org.apache.spark.sql.hive.HiveContext(sc)

sqlContext.sql(“select count(*) from test.sample”).collect()

堆栈跟踪：

堆栈SQL上下文可用作sqlContext。

scala> sqlContext.sql("select count(*) from test.sample").collect()

我使用的是hadoop 2.6.0，spark 1.6.0，hive 1.2.1，hbase 0.98.9

我在hadoop-env.sh中将此设置添加为

export HADOOP_CLASSPATH=$HADOOP_CLASSPATH:$HBASE_HOME/lib/*

有人可以建议任何解决方案

Answer 1

java.lang.NoClassDefFoundError: org/apache/hadoop/hbase/util/Bytes

因为类路径中没有与hbase相关的jar文件

 export HADOOP_CLASSPATH=$HADOOP_CLASSPATH: `hbase classpath`

应该包含所有与hbase相关的jar文件或者使用--jars

在此处查看我的answer

注意：要验证类路径，您可以在驱动程序中添加以下代码以打印所有类路径资源

scala版本：

val cl = ClassLoader.getSystemClassLoader
    cl.asInstanceOf[java.net.URLClassLoader].getURLs.foreach(println)

java：

import java.net.URL;

import java.net.URLClassLoader;
...

   ClassLoader cl = ClassLoader.getSystemClassLoader();

        URL[] urls = ((URLClassLoader)cl).getURLs();

        for(URL url: urls) {
            System.out.println(url.getFile());
        }

Answer 2

我得到了它的工作。你必须使用以下罐子。

spark-shell --master yarn-client --executor-cores 10 --executor-memory 20G --num-executors 15 --driver-memory 2G --driver-class-path /usr/hdp/current/hbase-client/lib/hbase-common.jar:/usr/hdp/current/hbase-client/lib/hbase-client.jar:/usr/hdp/current/hbase-client/lib/hbase-server.jar:/usr/hdp/current/hbase-client/lib/hbase-protocol.jar:/usr/hdp/current/hbase-client/lib/guava-12.0.1.jar:/usr/hdp/current/hbase-client/lib/htrace-core-3.1.0-incubating.jar --jars /usr/hdp/current/hbase-client/lib/hbase-client.jar,/usr/hdp/current/hbase-client/lib/hbase-common.jar,/usr/hdp/current/hbase-client/lib/hbase-server.jar,/usr/hdp/current/hbase-client/lib/guava-12.0.1.jar,/usr/hdp/current/hbase-client/lib/hbase-protocol.jar,/usr/hdp/current/hbase-client/lib/htrace-core-3.1.0-incubating.jar,/usr/hdp/current/hive-client/lib/hive-hbase-handler.jar --files /etc/spark/conf/hbase-site.xml

SparkSQL + Hive + Hbase + HbaseIntegration不起作用
