Best YARN Lecture. Sir, Can you please explain? How to configure capacity-scheduler for queue for submit multiple spark application at same time? Or any other suggestion to run multiple application on Hadoop yarn cluster. Please

[@junaidansari675]

superb explaination

@2:20 application manager try to find out container first by
communicating with node manager . @4:04 After finding free container Application manager will launch Application master
for that container.
@23:55 you tell resource manager will launch contrainer for the MRApplication Master
so that it can host task on those container . then what happen to that container which
was create node manager at @20:39
please make few things clear
1)Resource Manager talk to Node manager and find container .
or
2)Resource Manager random launch MRApplication Master on any Datanode by communicating with NodeManager and then launch container on datanode for completing and monitoring task perform by MRApplication Master.

[@susantsahoo5853]

do you have the answer.. if yes, please share

[@praveenreddy1898]

@@susantsahoo5853 look at this ua-cam.com/video/7ooZ4S7Ay6Y/v-deo.html will probably help you and based on hadoop.apache.org/docs/current/hadoop-yarn/hadoop-yarn-site/YARN.html The ApplicationsManager is responsible for accepting job-submissions, negotiating the first container for executing the application specific ApplicationMaster and provides the service for restarting the ApplicationMaster container on failure. The per-application ApplicationMaster has the responsibility of negotiating appropriate resource containers from the Scheduler, tracking their status and monitoring for progress.

[@yasim9435]

When ApM no requested container at the node where data is stored, but RM not able to find any , ApM is given container and has to process data over remote access. In case of network failures in remote access, who and what actions are taken?

[@SrikantShirisha]

Another question I have is what is the resource manager died but the data was processed and manipulated and is no longer in its original state?

[@hetadesai7938]

Does it copies the data to container when assigning a container randomly in case no container is available on node where data relies ?

[@bvb6914]

How many container could be launch in one node?

[@samirapathan8196]

If container is not available on any datanode then how resources manager generate new container on any datanode??

[@tushibhaque863]

Awesome

[@ganeshgokhale1657]

please try to explained Hadoop Resource manager High availability in deep.

[@shivrajshetty9827]

Y do we copy Job resources to HDFS, when we say HDFS u mean to say Name node??

[@jagdishmathpal2478]

Can You Please give some more clarity for Application Flow Step 1 to-4 and the how the result submitted to the Client back

[@ishanvarshney9054]

much better than edureka!

[@SrikantShirisha]

Difference between yarn and map reduce?

[@abusufiyan930]

map reduce is single point of failure yarn is not single point
