必须的环境变量 HIVE_CONF_DIR 不存在！

理论上来说, 按照 DataSphereStudio 的官方文档, 把相应的环境变量都设置了的

###HADOOP CONF DIR #/appcom/config/hadoop-config
HADOOP_CONF_DIR=/home/hadoop/hadoop-2.7.2/etc/hadoop
###HIVE CONF DIR  #/appcom/config/hive-config
HIVE_CONF_DIR=/home/hadoop/apache-hive-2.3.3-bin/conf
###SPARK CONF DIR #/appcom/config/spark-config
SPARK_CONF_DIR=/home/hadoop/spark-2.4.8-bin-hadoop2.7/conf

但仍然报错如下:

分析源码: 

ProcessEngineConnLaunch.scala:115 

  -- BDPConfiguration

  -- val DEFAULT_PROPERTY_FILE_NAME = "linkis.properties"

找到 linkis.properties 文件相应的配置是小写带点

#hadoop/hive/spark config
hadoop.config.dir=/home/hadoop/hadoop-2.7.2/etc/hadoop
hive.config.dir=/home/hadoop/apache-hive-2.3.3-bin/conf
spark.config.dir=/home/hadoop/spark-2.4.8-bin-hadoop2.7/conf

拿法: 

val propsValue =  sysProps.get(key).orElse(sys.props.get(key))

解决办法: 我们把  HIVE_CONF_DIR 放进环境变量

vi /etc/profile

在行尾写入以下内容

export HIVE_CONF_DIR=/home/hadoop/apache-hive-2.3.3-bin/conf

保存后

source /etc/profile


通过如下命令检查是否正确

echo $HIVE_CONF_DIR

输出  /home/hadoop/apache-hive-2.3.3-bin/conf

重启服务

cd /home/hadoop/dss_linkis/bin
sh stop-all.sh 
sh start-all.sh

发现日志文件 linkis-cg-entrance.log 有警告:

根据20.log这个文件,看到报错

NestedThrowablesStackTrace:
java.lang.ClassNotFoundException: org.datanucleus.api.jdo.JDOPersistenceManagerFactory

这个错误写的很明确,就是找不到这个类, 那么环境变量下面肯定没有

我们在HIVE_HOME/lib 发现 datanucleus-api-jdo-4.2.4.jar 这个jar包是存在, 但是报错信息显示不存在, 那么显然不是从这里找的, 根据如下错误栈分析

find . -name linkis-engineplugin-hive-1.1.1.jar

找到文件

./linkis-engineconn-plugins/hive/dist/v2.3.3/lib/linkis-engineplugin-hive-1.1.1.jar
./linkis-engineconn-plugins/hive/plugin/2.3.3/linkis-engineplugin-hive-1.1.1.jar

在目录

./linkis-engineconn-plugins/hive/dist/v2.3.3/lib/ 看到了hive-exec-2.3.3.jar 

这里面不用去找, 直接猜 缺少的 jar 包 datanucleus-api-jdo-4.2.4.jar 应该跟 hive-exec-2.3.3.jar 在一块

于是 cp $HIVE_HOME/lib/datanucleus-api-jdo-4.2.4.jar ./

然后再跑发现报错信息变了, 在意料之中, 因为拷贝的时候少拷贝了jar包 

2023-08-17 15:07:25.069 ERROR [Linkis-Default-Scheduler-Thread-10] DataNucleus.Datastore 125 error - Exception thrown creating StoreManager. See the nested exception org.datanucleus.exceptions.NucleusUserException: There is no available StoreManager of type "rdbms". Make sure that you have put the relevant DataNucleus store plugin in your CLASSPATH and if defining a connection via JNDI or DataSource you also need to provide persistence property "datanucleus.storeManagerType"

执行

cp $HIVE_HOME/lib/datanucleus-rdbms-4.1.19.jar ./

报错信息变成其它,请在后续文章查看解决办法
