Exchang组件yarn-cluster模式导入报错,java.lang.ClassNotFoundException: com.vesoft.nebula.exchange.Exchange

nebula 版本:v2.6.2
部署方式:分布式 (3节点)
安装方式:RPM
是否为线上版本:N
硬件信息
磁盘: HHD+SSD 500G
CPU、内存信息: 48C / 100G
问题的具体描述:老师们好,请教一个exchange问题哈,使用exchange导入数据的时候,同一个space同一份数据多次导入不是覆盖插入吗?为什么我上面操作的时候是增量插入的呢?(一份数据30G,导入了3次,集群中每个节点的数据量变成了30*3=90G)

Nebula Exchange v2.6.3版本
Spark v2.4.0版本
CDH v6.3.2版本

使用exchange组件,导入hdfs中的csv数据文件到nebula数据库中。使用local模式或yarn-client模式都提交正常,使用yarn模式的cluster提交时报错,spark提交命令如下:
spark-submit --master yarn
–deploy-mode cluster
–driver-memory=2G
–num-executors=10
–executor-memory=6G
–executor-cores=6
–class com.vesoft.nebula.exchange.Exchange
nebula-exchange-2.6.3.jar -c hdfs://nameservice1/nebula_data/app_sf30.conf

报错信息如下:

看下readme哦,有说明yarn cluster模式下怎么使用。
原因是yarn cluster模式下会随机选择一个机器作为driver,作为driver的那个机器中没有exchange的jar包。

谢谢老师,ReadMe中介绍的比较简单,没有对jar包和配置文件位置做特殊说明,这种默认都是在本地服务器目录吧?

你用这个 你圈出来的命令的话,jar包和配置文件就放在 执行spark-submit命令的机器本地就好了

使用这个命令会报错:
spark-submit --class com.vesoft.nebula.exchange.Exchange \ --master yarn-cluster \ --files app_sf30.conf \ nebula-exchange-2.6.3.jar \ -c app_sf30.conf

我将jar包放到hdfs上面,用下面的命令提交运行,也是找不到主类:

spark-submit --master yarn \
--deploy-mode cluster \
--driver-memory=2G \
--num-executors=10 \
--executor-memory=6G \
--executor-cores=6 \
--class com.vesoft.nebula.exchange.Exchange \
hdfs://nameservice1/nebula_data/nebula-exchange-2.6.3.jar \
-c hdfs://nameservice1/nebula_data/app_sf30.conf 

错误信息:java.lang.ClassNotFoundException: com.vesoft.nebula.exchange.Exchange

你为什么不用readme中给出的命令啊, 你少了两个–conf 配置

老师好,我用了一样的命令也是返回错误的:

换用另一种方式调用也不行,麻烦老师再帮忙看下 :cold_sweat:


执行命令的当前目录下有exchange的jar包吗

有的老师,jar和配置文件都在当前目录下。

这是当前目录:
2Z7O_A8E}XVPJ}{Y~76T@3

如果你在A机器的当前目录下执行spark-submit 目录,加上–conf spark.driver.extraClassPath后会从你当前目录下找jar包并读取主类Exchange,不应该找不到类呀

有点奇怪,如果位置有问题应该提示找不到jar包吧?现在一直提示类找不到java.lang.ClassNotFoundException: com.vesoft.nebula.exchange.Exchange
我把详细信息发一下哈!

当前目录:

如果Spark的应用程序包不在,只会提示主类找不到,不会提示jar包找不到的。 你可以用本地模式随便找个目录测试一下就可以验证了。

我刚试了下 上面的提交命令是可以的,可能你要看下你的yarn集群中其他机器是否有对jar包的访问权限

我在一个不存在jar包的目录中运行上述命令,提示的是file not exist.

请教下老师这个怎么验证?目前这种yarn-cluster的提交方式,是会将jar包同步到集群上,然后各个节点机器再去读取使用对吧?有办法验证没 :lying_face:

file not exist是因为你的测试目录下不仅没有jar包也没有配置文件,这个错误是指配置文件不存在,你看我测试结果。
在test目录下有配置文件没有jar包,提示的是ClassNotFoundException

运行exchange后在spark的webui界面查看下 environment 里面有System property,看此时的用户是谁,然后确认下该用户是否有extraClassPath的访问权限

老师好,抱歉应该是我这边包的问题,这里显示的大小是0 :cold_sweat:
我再排查下
