查看文档，我看到可用的泛型参数列表如下：

Generic options supported are
-conf <configuration file>     specify an application configuration file
-D <property=value>            use value for given property
-fs <local|namenode:port>      specify a namenode
-jt <local|jobtracker:port>    specify a job tracker
-files <comma separated list of files>    specify comma separated files to be copied to the map reduce cluster
-libjars <comma separated list of jars>    specify comma separated jar files to include in the classpath.
-archives <comma separated list of archives>    specify comma separated archives to be unarchived on the compute machines.

我想在sqoop命令中指定以下两个属性：

mapred.job.queuename=batch 
mapred.child.java.opts="\-Djava.security.egd=file:///dev/urandom"

所以我写了导入sqoop脚本如下：

sqoop import -Dmapred.job.queuename=batch \
        mapred.child.java.opts="\-Djava.security.egd=file:///dev/urandom" \
        --connect $connection \
        --username $username\
        --password $password \
        --table $sourceTable \
        --columns "$columns"\
        --hive-import \
        --hive-overwrite \
        --hive-table $targetTable \
        --compression-codec org.apache.hadoop.io.compress.SnappyCodec \
        --hive-delims-replacement "SPECIAL" \
        --null-string '\\N' \
        --null-non-string '\\N' \
        -m 1

但它不起作用。。。

我也想过做以下的事情

sqoop import \
        -D mapred.job.queuename=batch \
        -D mapred.child.java.opts="\-Djava.security.egd=file:///dev/urandom" \
        --connect $connection \
        --username $username \
        --password $password \
        --table $sourceTable \
        --columns "$columns"\
        --hive-import \
        --hive-overwrite \
        --hive-table $targetTable \
        --compression-codec org.apache.hadoop.io.compress.SnappyCodec \
        --hive-delims-replacement "SPECIAL" \
        --null-string '\\N' \
        --null-non-string '\\N' \
        -m 1

但恐怕只有一个二维泛型参数会被解析。
哪种方法是正确的？
