Spark+Hive的example运行问题
最近做实验需要收集Spark+Hive的一些指令trace,但在运行Spark自带的Scala版Hive样例代码时出问题。
Hive环境我已经配置了,并且试着执行,创建数据文件试着执行了create table和select等语句,测试成功了。然后我将hive-site.xml拷贝到spark/conf目录下,使用命令:
./bin/run-example org.apache.spark.examples.sql.hive.HiveFromSpark --driver-class-path $SPARK_HOME/lib/mysql-connector-java-5.1.34-bin.jar
执行后报错如下:
14/11/27 09:59:12 ERROR metastore.RetryingRawStore: JDO datastore error. Retrying metastore command after 1000 ms (attempt 1 of 1)

我把输出的log都复制过来了,所以有点长 =。=
我在这里 http://find.searchhub.org/document/4337487133fe5d80#9a32608a1d5a709f 看到了一些解答但是还是很含糊,求大神解答!!
使用
spark-shell --driver-class-path ./lib/mysql-connector-java-5.1.34-bin.jar
启动交互命令行,将scala版example下的sql/hive/HiveFromSpark的代码一行行执行,能够正常执行,但是怎么直接run-example运行就报错呢?
Answers
好坑,这里有好几个坑,一一说明:
-
首先,我给hive配的Mysql作为元数据服务器,因此需要对应的jar包,也就是在上面看到的--driver-class-path ./lib/mysql-connector-java-5.1.34-bin.jar 参数。一开始是没有的,这是第二次编辑的时候加上去的。
-
加了之后仍然报错,也就是上面的错误提示。spark给的默认代码中使用的是
val hiveContext = LocalHiveContext(sc)
,我这里配Hive配的是远程模式,不是本地模式,因此改为val hiveContext = HiveContext(sc)
,当然也要对应的import HiveContext包了。 -
修改了源码还不够,需要将修改的源码重新打包编译,然后使用spark-submit 来提交任务执行。具体的方法可以搜网上的。
以上就是上面的问题的解决思路。
