oozie调度插件的使用(三) Oozie 和 Hue 整合
1. 修改 hue 配置文件 hue.ini
cd /export/servers/hue-3.9.0-cdh5.14.0/desktop/conf
[liboozie]
# The URL where the Oozie service runs on. This is required in order for
# users to submit jobs. Empty value disables the config check.
oozie_url=http://hadoop01:11000/oozie
# Requires FQDN in oozie_url if enabled
## security_enabled=false
# Location on HDFS where the workflows/coordinator are deployed when submitted.
remote_deployement_dir=/user/root/oozie_works
[oozie]
# Location on local FS where the examples are stored.
## local_data_dir=..../examples
# Location on local FS where the data for the examples is stored.
## sample_data_dir=...thirdparty/sample_data
# Location on HDFS where the oozie examples and workflows are stored.
# Parameters are $TIME and $USER, e.g. /user/$USER/hue/workspaces/workflow-$TIME
## remote_data_dir=/user/hue/oozie/workspaces
# Maximum of Oozie workflows or coodinators to retrieve in one API call.
oozie_jobs_count=100
# Use Cron format for defining the frequency of a Coordinator instead of the old frequency number/unit.
enable_cron_scheduling=true
# Flag to enable the saved Editor queries to be dragged and dropped into a workflow.
enable_document_action=true
# Flag to enable Oozie backend filtering instead of doing it at the page level in Javascript. Requires Oozie 4.3+.
enable_oozie_backend_filtering=true
# Flag to enable the Impala action.
enable_impala_action=true
[filebrowser]
# Location on local filesystem where the uploaded archives are temporary stored.
archive_upload_tempdir=/tmp
# Show Download Button for HDFS file browser.
show_download_button=true
# Show Upload Button for HDFS file browser.
show_upload_button=true
# Flag to enable the extraction of a uploaded archive in HDFS.
enable_extract_uploaded_archive=true
2. 启动 hue、oozie
启动 hue 进程
cd /export/servers/hue-3.9.0-cdh5.14.0
build/env/bin/supervisor
启动 oozie 进程
cd /export/servers/oozie-4.1.0-cdh5.14.0
bin/oozied.sh start
页面访问 hue
3.Hue 集成 Oozie
3.1 使用 hue 配置 oozie 调度
hue 提供了页面鼠标拖拽的方式配置 oozie 调度

3.2 利用 hue 调度 shell 脚本
在 HDFS 上创建一个 shell 脚本程序文件。



打开工作流调度页面。






3.3 利用 hue 调度 hive 脚本
在 HDFS 上创建一个 hive sql 脚本程序文件。

打开 workflow 页面,拖拽 hive2 图标到指定位置。





3.4 利用 hue 调度 MapReduce 程序
利用 hue 提交 MapReduce 程序



参数:
mapred.mapper.new-api = true
mapred.reducer.new-api = true
指定 MR 的输出 key 的类型
mapreduce.job.output.key.class = org.apache.hadoop.io.Text
指定 MR 的输出的 value 的类型
mapreduce.job.output.value.class = org.apache.hadoop.io.IntWritable
指定输入路径
mapred.input.dir = 路径名称
mapred.output.dir = 路径名称
指定执行的 map 类
mapreduce.job.map.class = org.apache.hadoop.examples.WordCount$TokenizerMapper
指定执行的 reduce 类
mapreduce.job.reduce.class = org.apache.hadoop.examples.WordCount$IntSumReducer
配置 map task 的个数
mapred.map.tasks = 1
3.5 利用 Hue 配置定时调度任务
在 hue 中,也可以针对 workflow 配置定时调度任务,具体操作如下:




一定要注意时区的问题,否则调度就出错了。保存之后就可以提交定时任务。


点击进去,可以看到定时任务的详细信息。


4. Oozie 任务查看、杀死
查看所有普通任务
oozie jobs
查看定时任务
oozie jobs -jobtype coordinator
杀死某个任务 oozie 可以通过 jobid 来杀死某个定时任务
oozie job -kill [id]
oozie job -kill 0000085-180628150519513-oozie-root-C
