我使用的是hadoop 1.0.3和sqoop 1.4.6。我正在尝试将一个表从MySQL导入到hdfs。我收到以下错误:
Exception in thread "main" java.lang.IncompatibleClassChangeError: Found class org.apache.hadoop.mapreduce.JobContext, but interface was expected
at org.apache.sqoop.config.ConfigurationHelper.getJobNumMaps(ConfigurationHelper
我尝试从oracle到Hive执行sqoop表操作,但是当我发出sqoop命令时,它能够连接数据库并获取reocd,但是当它获取用于在Hive中创建表的元数据时,它失败了,并出现以下异常。当我浏览这个问题时,每个人都说这是与大小写敏感的问题有关的东西,但我尝试了所有的可能性,但最终没有解决方案。
例外:
java.lang.NullPointerException

目前,我已经下载了datastax企业版4.0,并使用了dse sqoop将SQL Server迁移到Cassandra,我得到了以下错误:

几天来,我一直在使用sqoop将数据从oracle数据库导入hadoop集群。
现在,当我尝试执行sqoop导入时,我得到了以下错误:

我下载了sqljdbc4.jar。我像这样从文件夹(存储jar的地方)调用sqoop:
sqoop list-tables --driver com.microsoft.jdbc.sqlserver.SQLServerDriver --connect jdbc:sqlserver://localhost:1433;user=me;password=myPassword; -libjars=./sqljdbc4.jar
我收到以下警告和错误:

在执行此命令时获取以下错误。附加了sqoop/lib文件夹文件。
