Question

我正在尝试从具有2000列的TERADATA表中将数据导入HDFS（表定义生成90K字符）...当我执行我的脚本时，我得到：

/tmp/sqoop-hadoopi/compile/636c527afc3baa6fdf33464f02430602/table.java:21971: code too large

我的sqoop脚本：

sqoop import \
 -libjars $LIB_JARS \
 --connect jdbc:teradata://PRD/Database=database \
 --connection-manager org.apache.sqoop.teradata.TeradataConnManager \
 --table table \
 --username login \
 --password pass \

我的输出日志：

也许有人已经进口了一张大桌子...... 非常感谢！

Answer 1

Java中的每个方法都限制为64KB的字节码。我担心当前版本的Sqoop没有设施可以将你的案例中生成的长方法分解为多个子方法，所以我建议在Sqoop JIRA上打开一个新的功能请求。

Answer 2

我不知道你是否已经尝试过这个，但是有用于Hadoop的Teradata Connector：
