报错一:

背景

启动spark-shell后查询hive中的表信息，报错

$SPARK_HOME/bin/spark-shell
spark.sql("select * from student.student ").show()

日志

Caused by: java.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.ql.metadata.SessionHiveMetaStoreClient
    at org.apache.hadoop.hive.metastore.MetaStoreUtils.newInstance(MetaStoreUtils.java:1523)
    at org.apache.hadoop.hive.metastore.RetryingMetaSto

    Caused by: org.datanucleus.store.rdbms.connectionpool.DatastoreDriverNotFoundException:
    The specified datastore driver ("com.mysql.jdbc.Driver") was not found in the 
    CLASSPATH. Please check your CLASSPATH specification, 
    and the name of the driver.

原因:

spark访问存放hive的Metastore的mysql数据库时，没有连接成功，因为spark没有没有mysql-connecter的jar包，即mysql驱动

解决:

有人说，那就直接把jar包cp到$SPARK_HOME/jars下呗，不好意思，这样再生产中是绝对不行的，并不是所有spark程序都会用到mysql驱动，所以我们要在提交作业时指定--jars，多个jar包用逗号分隔注(我的mysql版本是5.1.73)

此时我们也可以在ui界面上看一下是不是将mysql驱动包添加到该任务中了
Spark SQL 报错总结

Spark SQL 报错总结
发现的确添加成功

报错二:

背景

启动spark-sql时，发生报错

spark-sql

日志

19/05/21 08:54:14 ERROR Datastore.Schema: Failed initialising database.
Unable to open a test connection to the given database. 
JDBC url = jdbc:mysql://192.168.1.201:3306/hiveDB?createDatabaseIfNotExist=true, username = root. Terminating connection pool 
(set lazyInit to true if you expect to start your database after your app).
Original Exception: ------
java.sql.SQLException: No suitable driver found for jdbc:mysql://192.168.1.201:3306/hiveDB?createDatabaseIfNotExist=true

Caused by: java.sql.SQLException: No suitable driver found for
jdbc:mysql://192.168.1.201:3306/hiveDB?createDatabaseIfNotExist=true

原因

driver端没有mysql驱动，连接不上hive的元数据。

解决

查看一下我的启动命令，发现已经使用--jars指定了mysql驱动包的路径
并且根据spark-sql --help的说明,可以将指定得jar包都添加到driver 和 executor的classpaths

--jars JARS                 Comma-separated list of jars to include on the driver and executor classpaths.

但是driver的classpath依旧没有mysql的驱动，这是为什么呢？暂时不得而知，，所以，我尝试了一下，启动时另外添加driver的classpath路径

 spark-sql --jars softwares/mysql-connector-java-5.1.47.jar --driver-class-path softwares/mysql-connector-java-5.1.47.jar

启动成功~，看来官方解释也不一定就是准确的呀，还是要实测！小坑

报错三:

背景

在IDEA中将RDD转换成为DataFrame时，在代码没有问题的情况下(同段代码在spark-shell测试成功)发生报错。
代码如下:

object SparkSessionDemo {

  /**
    * 创建SparkSession，测试
    *
    * @param args
    */
  def main(args: Array[String]): Unit = {

    val spark=SparkSession
      .builder()
      .master("local[*]")
      .appName("SparkSessionDemo")
      .getOrCreate()

    import spark.implicits._
    val logs=spark.sparkContext.textFile("file:///D:/cleaned.log ") .map(_.split("\t"))
      val logsDF=logs.map(x=>CleanedLog(x(0),x(1),x(2),x(3),x(4),x(5),1L,x(6),x(7))).toDF()

    logsDF.show()

  }
  case class CleanedLog(cdn:String,region:String,level:String,date:String,ip:String, domain:String, pv:Long,url:String, traffic:String)

}

控制台报错日志

一共是两次报错，但是原因相同，为了节约空间，我放到一起了

一、
Exception in thread "main" java.lang.NoClassDefFoundError:
org/codehaus/janino/InternalCompilerException
...
Caused by: java.lang.ClassNotFoundException: org.codehaus.janino.InternalCompilerException
    at java.net.URLClassLoader.findClass(URLClassLoader.java:381)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:424)
    at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:357)
    ... 33 more
二、
Exception in thread "main" java.lang.NoSuchMethodError:
org.codehaus.commons.compiler.Location.<init>(Ljava/lang/String;II)V

原因：

jar包冲突
spark-sql-2.4.2需要的janino和compiler包和hive-1.1.0需要的版本不一致，由于hive的版本过低，并且比spark-sql先添加到pom.xml中，所以当发生jar包冲突时默认使用hive中使用的jar包。

解决：

使用maven helper插件，将冲突jar包janino、compiler的低版本添加exclusion标签，具体做法请参照我另一篇博客IDEA-plugin 之解决maven工程jar冲突必备良药 Maven Helper
运行成功之后是这样滴
