1.錯誤：Sqoop:Import failed: java.lang.ClassNotFoundException: org.apache.hadoop.hive.conf.HiveConf

解決方法1：

將mysql中的數據導入到hive中報錯：

這是因為sqoop需要一個hive的包，將hive/lib中的hive-common-2.3.3.jar拷貝到sqoop的lib目錄中，重新執行試試。

解決方法2：

在/etc/profile中添加下面一行

export HADOOP_CLASSPATH=$HADOOP_CLASSPATH:$HIVE_HOME/lib/*

2.錯誤：main ERROR Could not register mbeans java.security.AccessControlException: access denied ("javax.management.MBeanTrustPermission" "register")

解決方法：

Just add the following lines to your java.policy file unter <JRE_HOME>/lib/security.
grant {
　　permission javax.management.MBeanTrustPermission "register";
};

3.錯誤：ERROR exec.DDLTask: java.lang.NoSuchMethodError: com.fasterxml.jackson.databind.ObjectMapper.readerFor(Ljava/lang/Class;)Lcom/fasterxml/jackson/databind/ObjectReader;

解決犯法：jackson jar包版本沖突，將sqoop/lib下的jackson*.jar備份，將hive/lib包下的jackson*.jar包拷貝過來

4.錯誤：Required table missing : "DBS" in Catalog "" Schema "". DataNucleus requires this table to perform its persistence operations. Either your MetaData is incorrect, or you need to enable "datanucleus.schema.autoCreateTables"

解決方法：

到hive-site.xml中找到datanucleus.schema.autoCreateAll 把value改成true
