问题 We work with Cloudera cdh 5.4.0, and have been trying to trigger a oozie job from Java API to send out emails. There is a dependency on two 3rd party jar files - activation.jar and mail.jar for the email to be send out using the SMTP Login.

阅读更多关于 Questions about Oozie/Sqoop

问题 I have few questions: 1. Why is there MapReduce process in Sqoop to load data from HDFS to MySQL? e.g. Data is in HDFS on directory: /foo/bar To load data in MySQL bar table, why is there a MapReduce process? sqoop export --connect jdbc:mysql://localhost/hduser --table foo -m 1 --export-dir /foo/bar After entering above command, MapReduce process executes. 2. How can I enable/disable key in MySQL using Sqoop/Oozie? Since huge data is getting loaded to MySQL, we need to use enable/disable. How

How to change value in an oozie job coordinator?

阅读更多关于 How to change value in an oozie job coordinator?

问题 I have a mapreduce job which is scheduled by an oozie coordinator and runs every 4 hours. This mapreduce job takes a parameter, let's say k, whose value is set in the job.config file. I'd like to know if I change the value of this parameter between two runs, does it pick the updated (new) value or it sticks to the original (old) value? 回答1: if the job is in runing mode, it will stick to Old parameter it self, and if the job is in waiting to schedule run, then it will take the latest value :).

My ssh action looks like that :

Multiple JAVA actions in Oozie workflow

阅读更多关于 Multiple JAVA actions in Oozie workflow

问题 I read the documentation that it isn't possible to create a loop in a workflow, but I need to invoke the main method separately each time with the list item - hence need to create a loop. One solution was to invoke the workflow again using sub-workflow. Is there any other solution to this? Like using coordinator jobs? 回答1: Some possible 'hack' solutions that i can think of: Create a custom java action as you say, that uses the Oozie Client API to run several workflows (one for each item in

Oozie file based coordinator

In case the file was not created, the coordinator should wait until the file is created.
