2000 列の TERADATA テーブルから HDFS にデータをインポートしようとしています (テーブル定義は 90K 文字になります)...スクリプトを実行すると、次のようになります。
/tmp/sqoop-hadoopi/compile/636c527afc3baa6fdf33464f02430602/table.java:21971: code too large
私のスクープスクリプト:
sqoop import \
-libjars $LIB_JARS \
--connect jdbc:teradata://PRD/Database=database \
--connection-manager org.apache.sqoop.teradata.TeradataConnManager \
--table table \
--username login \
--password pass \
私の出力ログ:
