sqoop出口本地CSV到MySQL错误MapReduce的

Question

我试图本地CSV文件导出到MySQL表“测试”：

$ 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 

不过，我有一个奇怪的错误说mapreduce.tar.gz未发现：

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.

该文件但可在我的本地机器：

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

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

任何人都知道问题是什么？我只是按照本指南：

酒店mapreduce.application.framework.path有这个值/hdp/apps/2.5.0.0-1245/mapreduce/mapreduce.tar.gz在mapred-site.xml集。这是MapReduce框架归档的路径，并指向HDFS中的文件。

这里，Sqoop正在触发-fs local此属性需要设置一个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
