mysql - sqoop 将本地 csv 导出到 mapreduce 上的 MySQL 错误

Question

我试图将本地 csv 文件导出到 MySQL 表“test”:

$ sqoop export -fs local -jt local --connect jdbc:mysql://172.16.21.64:3306/cf_ae07c762_41a9_4b46_af6c_a29ecb050204 --username username --password password --table test --export-dir file:///home/username/test.csv

但是，我收到一个奇怪的错误提示 mapreduce.tar.gz not found:

Warning: /usr/hdp/2.5.0.0-1245/hbase does not exist! HBase imports will fail.
Please set $HBASE_HOME to the root of your HBase installation.

然而，该文件在我的本地机器上可用:

/usr/hdp/2.5.0.0-1245/hadoop/mapreduce.tar.gz

/data/hadoop/yarn/local/filecache/13/mapreduce.tar.gz

谁知道是什么问题？我只是在遵循本指南:

属性 mapreduce.application.framework.path 在 /hdp/apps/2.5.0.0-1245/mapreduce/mapreduce.tar.gz 中设置了这个值 mapred-site.xml。这是 MapReduce 框架存档的路径，指向 HDFS 中的文件。

在这里，Sqoop 被-fs local 触发，这个属性需要设置一个LocalFS 路径。尝试使用 mapreduce 存档文件的本地路径覆盖此属性值。

$ sqoop export -fs local -jt local -D 'mapreduce.application.framework.path=/usr/hdp/2.5.0.0-1245/hadoop/mapreduce.tar.gz' --connect jdbc:mysql://172.16.21.64:3306/cf_ae07c762_41a9_4b46_af6c_a29ecb050204 --username username --password password --table test --export-dir file:///home/username/test.csv
