sqoop導出mysql分區

Question

我想使用sqoop從分區配置表導出到mysql。

起初，我試着做

$sqoop export --connect jdbc:mysql://<server addr>/<db name> --username <user name> -P --table source_edge_daily --export-dir /path/to/table/<table name> --input-fields-terminated-by '\t' --verbose 

的指揮失誤了說

Open failed for file /path/to/table/<table name>/<partition name>, attempt to open a directory 

當我指向分區目錄

$sqoop export --connect jdbc:mysql://<server addr>/<db name> --username <user name> -P --table source_edge_daily --export-dir /path/to/table/<table name>/<partition name> --input-fields-terminated-by '\t' --verbose 

命令失敗說

我也試過重新創建MySQL表沒有分區鍵，創建一個分區的MySQL表，一切失敗，出現相同的錯誤消息
