我正在使用hpd-2.4.2，并尝试使用oozie协调器作业向外部配置单元表添加分区。我创建了一个协调器，每天执行以下工作流程：

<workflow-app name="addPartition" xmlns="uri:oozie:workflow:0.4">
  <start to="hive"/>
  <action name="hive">
   <hive2 xmlns="uri:oozie:hive2-action:0.1">
    <job-tracker>${jobTracker}</job-tracker>
    <name-node>${nameNode}</name-node>
    <jdbc-url>jdbc:hive2://${jdbcPath}</jdbc-url>
    <password>yarn</password>
    <script>${appPath}/addPartition.q</script>
    <param>nameNode=${nameNode}</param>
    <param>dt=${dt}</param>
    <param>path=${path}</param>
   </hive2>
   <ok to="end" />
   <error to="fail" />
  </action>
  <kill name="fail">
   <message>
    Workflow failed, error message[${wf:errorMessage(wf:lastErrorNode())}]
   </message>
  </kill>
  <end name="end" />
</workflow-app>

执行的脚本包含

CREATE EXTERNAL TABLE IF NOT EXISTS visits (sid BIGINT, os STRING, browser STRING, visit_time TIMESTAMP)
  PARTITIONED BY (dt STRING) 
  STORED AS PARQUET;
ALTER TABLE visits ADD PARTITION(dt = '${dt}') LOCATION   '${nameNode}/data/parquet/visitors/${path}';

如果我运行该作业，则会创建表，但不会添加分区。我发现：

Beeline command arguments :
         -u
         jdbc:hive2://localhost:10000/default
         -n
         yarn
         -p
         yarn
         -d
         org.apache.hive.jdbc.HiveDriver
         --hivevar

         --hivevar

         --hivevar
         path=2016/01/05
         -f

>>> Invoking Beeline command line now >>>
[...]
0: jdbc:hive2://localhost:10000/default> ALTER TABLE visits ADD    PARTITION(dt = '${dt}') LOCATION  '${nameNode}/data/parquet/visitors/${path}';

似乎alter表中的参数没有被替换，为了检查这一点，我尝试直接从cli调用beeline：

beeline -u jdbc:hive2://localhost:10000/default -n yarn -p yarn -d org.apache.hive.jdbc.HiveDriver --hivevar nameNode=hdfs://bigdata01.local:8020 --hivevar dt="2016-01-03" --hivevar path="2016/01/03" -e "ALTER TABLE visits ADD PARTITION(dt='${dt}') LOCATION '${nameNode}/data/parquet/visitors/${path}';"

从而导致错误：

Connecting to jdbc:hive2://localhost:10000/default
Connected to: Apache Hive (version 1.2.1000.2.4.2.0-258)
Driver: Hive JDBC (version 1.2.1000.2.4.2.0-258)
Transaction isolation: TRANSACTION_REPEATABLE_READ
Error: Error while processing statement: FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask. partition spec is invalid; field dt does not exist or is empty (state=08S01,code=1)

如果我不带参数运行alter语句

beeline -u jdbc:hive2://localhost:10000/default -n yarn -p yarn -d org.apache.hive.jdbc.HiveDriver -e "ALTER TABLE visits ADD PARTITION(dt='2016-01-03') LOCATION 'hdfs://bigdata01.local:8020/data/parquet/visitors/2016/01/03';"

或者打开一个定义了hivevars的beeline控制台并执行alter语句

beeline -u jdbc:hive2://localhost:10000/default -n yarn -p yarn -d org.apache.hive.jdbc.HiveDriver --hivevar nameNode=hdfs://bigdata01.local:8020 --hivevar dt="2016-01-03" --hivevar path="2016/01/03"
0: jdbc:hive2://localhost:10000/default>  ALTER TABLE visits ADD PARTITION(dt = '${dt}') LOCATION '${nameNode}/data/parquet/visitors/${path}';

分区已创建。
我错在哪里？
更新：
hive2操作中参数的值在oozie.properties文件和coordinator.xml中定义

<property>
  <name>nameNode</name>
  <value>${nameNode}</value>
</property> 
<property>
 <name>dt</name>                
 <value>${coord:formatTime(coord:dateOffset(coord:nominalTime(), -1,'DAY'),'yyyy-MM-dd')}</value>
</property>
<property>
  <name>path</name>                    
  <value>${coord:formatTime(coord:dateOffset(coord:nominalTime(), -1,'DAY'),'yyyy/MM/dd')}</value>
</property>

在你找到的

Parameters:
------------------------
nameNode=hdfs://bigdata01.local:8020
dt=2016-01-05
path=2016/01/05

在hive2操作的直线调用中将它们设置为hivevars之前。
