我想在阿兹卡班做Hive工作
我可以上载配置单元作业，但配置单元作业未正确执行。

 ========================================================================

这是我的plugin.properties中的内容

job.class=azkaban.jobtype.hiveutils.azkaban.HiveViaAzkaban

hive.home=HIVE_HOME

hive.aux.jars.path=/usr/lib/hive/lib
env.HIVE_HOME=$HIVE_HOME
env.HIVE_AUX_JARS_PATH=/usr/lib/hive/lib

# hive.jvm.args=-Dhive.querylog.location=. -Dhive.exec.scratchdir=/tmp/hive-    ${user.to.proxy} -Dhive.aux.jars.path=${hive.aux.jars.path}

jobtype.global.jvm.args=${hive.jvm.args}

这是我的private.properties jobtype.classpath=$hadoop\u home/conf，$hadoop\u home/lib/，$hive\u home/lib/，$hive\u home/conf，/usr/lib/hive/lib jobtype.class=azkaban.jobtype.hadoopjavajob

hive.aux.jars.path=/usr/lib/hive/lib
env.HADOOP_HOME=$HADOOP_HOME
env.HIVE_HOME=$HIVE_HOME
env.HIVE_AUX_JARS_PATH=/usr/lib/hive/lib

hive.home=$HIVE_HOME

jobtype.global.classpath=${hive.classpath.items}
  hive.classpath.items=./*,${hive.home}/lib/*,${hive.home}/conf/,${hive.aux.jars.path}/*,${had    oop.home}/*,${hadoop.home}/lib/*,${hadoop.home}/conf/

我只在executor文件夹中添加了插件文件夹。
为什么不检测作业类型。请帮忙。
