我正在尝试为Spark Streaming项目设置开发环境,该项目需要将数据写入Hive.我有一个集群有1个主服务器,2个从服务器和1个开发机器(在Intellij Idea 14中编码).
在spark shell中,一切似乎都运行正常,我可以使用DataFrame.write.insertInto("testtable")通过Spark 1.5将数据存储到Hive中的默认数据库中
但是,当在IDEA中创建scala项目并使用具有相同设置的相同集群运行它时,在Metastore数据库中创建事务连接工厂时会抛出Error,该数据库假定在mysql中为"metastore_db".
这是hive-site.xml:
<configuration>
<property>
<name>hive.metastore.uris</name>
<value>thrift://10.1.50.73:9083</value>
</property>
<property>
<name>hive.metastore.warehouse.dir</name>
<value>/user/hive/warehouse</value>
</property>
<property>
<name>javax.jdo.option.ConnectionURL</name>
<value>jdbc:mysql://10.1.50.73:3306/metastore_db?createDatabaseIfNotExist=true</value>
</property>
<property>
<name>javax.jdo.option.ConnectionDriverName</name>
<value>com.mysql.jdbc.Driver</value>
</property>
<property>
<name>javax.jdo.option.ConnectionUserName</name>
<value>sa</value>
</property>
<property>
<name>javax.jdo.option.ConnectionPassword</name>
<value>huanhuan</value>
</property>
</configuration>
我运行IDEA的机器,可以远程登录Mysql和Hive来创建表,所以应该没有权限问题.这是log4j输出:
