私はインポート-すべてのテーブルをするsqoop経由しようとすると、私は次のエラーを取得しています中：

sqoopを輸入すべてのテーブルが12を-m - --username = retail_dba --password = Clouderaの--warehouse-DIR =/R/Clouderaの/ sqoop_import

Answer 1

ルックス "：mysqlの：//quickstart.cloudera 3306/retail_db JDBC" ここにコードを入力してください-connect同じようなアプリケーションのマスターは、繰り返し意味が殺されているので、彼らは好きなほどのメモリを得ることはできません。 cloudera仮想マシンでsqoopを試している場合は、-m 12を使用しないでください。これは、あなたが（単一の）マシンで処理できない12の並列マップタスクを起動しようとします。その設定をそのまま残すか、代わりに--directを試してみてください。また、--warehousedir=/r/cloudera/sqoop_importで何が起こっていますか？タイプミスとして/r/であるか、それは/user/

代わりにこれを試してみてくださいする必要があります：

sqoop import-all-tables \ 
--connect "jdbc:mysql://quickstart.cloudera:3306/retail_db" \ 
--warehouse-dir=/user/cloudera/sqoop_import 
--username=retail_dba \ 
--direct 
--password=cloudera; 

Answer 2

が輸入すべてのテーブルを使用している間、あなたのマッパーを制限しようとする。また、最初の1台に代わり輸入すべてのテーブルをロードしよう12人のマッパーがVM上のメモリを邪魔しています。

sqoop import-all-tables \ 
--connect "jdbc:mysql://quickstart.cloudera:3306/retail_db" \ 
--warehouse-dir=/user/cloudera/sqoop_import 
--username=retail_dba \ 
--password=cloudera 
-m 2
