<p class="MsoNormal">Hi all.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">We got several feedbacks about Sahara EDP’s future from some China customers.<u></u><u></u></p>
<p class="MsoNormal">Here are some ideas we would like to share with you and need your input if we can implement them in Sahara(Liberty).<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">1. Add a schedule feature to run the jobs on time:<u></u><u></u></p>
<p class="MsoNormal">This request comes from the customer, they usually run the job in a specific time every day. So it should be great if there is a scheduler to help arrange the regular job to run.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">2. A more complex workflow design in Sahara EDP:<u></u><u></u></p>
<p class="MsoNormal">Current EDP only provide one job that is running on one cluster.
<u></u><u></u></p>
<p class="MsoNormal">But in a real case, it should be more complex, they usually use multiple jobs to calculate the data and may use several different type clusters to process it.<u></u><u></u></p>
<p class="MsoNormal">For example: Raw Data -> Job A(Cluster A) -> Job B(Cluster B) -> Job C(Cluster A) -> Result<u></u><u></u></p>
<p class="MsoNormal">Actually in my opinion, this kind of job could be easy to implement by using Oozie as a workflow engine. But for current EDP, it doesn’t implement this kind of complex case.<u></u><u></u></p>
<p class="MsoNormal">Another concern is about Spark, for Spark it cannot use Oozie to do this. So we need to create an abstract layer to help to implement this kind of scenarios.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">However, any suggestion is welcome. <u></u><u></u></p>
<p class="MsoNormal">Thanks.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
