QUESTION

Unhealthy EMR nodes "local-dirs are bad: /mnt/yarn,/mnt3/yarn"

Asked 2020-Jul-07 at 18:30

I have a spark EMR cluster with 1 master and 8 Spot nodes. Today all the nodes dead while running a job, and spark-shell is also not assessable afterwards.

Click the 'Unhealthy Nodes' in hadoop console showing errors 2/4 local-dirs are bad: /mnt/yarn,/mnt3/yarn; 1/1 log-dirs are bad: /var/log/hadoop-yarn/containers

It seems related to the disk space issue in Why does Hadoop report "Unhealthy Node local-dirs and log-dirs are bad"? so I modified yarn-site.xml as described

Do you have termination protection on? If it's on the nodes cannot be automatically killed and restarted - see https://docs.aws.amazon.com/emr/latest/ManagementGuide/UsingEMR_TerminationProtection.html

QUESTION

HTTP-LoadBalancer constructed with Ingress on GKE is unstable between http-allowance and NOT http-allowance

Asked 2019-Feb-09 at 05:38

I'm trying to set HTTPS-LB, which is not allow to use HTTP, on GKE with Ingress.

Now, as described in a official site, I deployed a simple application on a private cluster. This application works that can be accessed with a browser. ※both by http-connection and https-connection

Then I prohibit a http-access to the application by turning a frontend's protocol "http" off (deletion) in a setting of the LB. Actually, at first, a http-connection via the browser got error, not connection-error. After a 5-10 mins, http-protocol setting is restored automatically.

Here is a yaml file.

If you could confirm which tutorial you’re following, we can confirm the test. Saying this, i think the behavior you are seeing could be expected.

According to GKE Ingress doc , it states:

"Whenever an HTTP(S) load balancer is configured through Ingress, you must not manually change or update the configuration of the HTTP(S) load balancer. That is, you must not edit any of the load balancer's components, including target proxies, URL maps, and backend services. Any changes that you make will be overwritten by GKE. "

You can try to delete the ingress, do the manual edit to your YAML file and recreate it again and see if the removal of HTTP works.

You haven't specified the version of Hadoop you are using. There is a JIRA on this issue and the fix is available from v2.9 onwards

https://issues.apache.org/jira/browse/YARN-4330?devStatusDetailDialog=repository

You can try setting the below parameters as per your system configuration.

There are two kinds of calculators currently available in YARN – the DefaultResourceCalculator and the DominantResourceCalculator.

The DefaultResourceCalculator only takes memory into account when doing its calculations. This is why CPU requirements are ignored when carrying out allocations in the CapacityScheduler by default. All the math of allocations is reduced to just examining the memory required by resource-requests and the memory available on the node that is being looked at during a specific scheduling-cycle.

In order to enable CPU scheduling, there are some configuration properties that administrators and users need to be aware of.

scheduler.capacity.resource-calculator: To enable CPU scheduling in CapacityScheduler, this should be set to org.apache.hadoop.yarn.util.resource.DominantResourceCalculator in capacity-scheduler.xml file. nodemanager.resource.cpu-vcores: Set to the appropriate number in yarn-site.xml on all the nodes. This is strictly dependent on the type of workloads running in a cluster, but the general recommendation is that admins set it to be equal to the number of physical cores on the machine. MapReduce framework has its own configurations that users should use in order to take advantage of CPU scheduling in YARN.

map.cpu.vcores: Set to the number of vcores required for each map task. reduce.cpu.vcores: Set to the number of vcores required for each reduce task. yarn.app.mapreduce.am.resource.cpu-vcores: Set to the number of vcores the MR AppMaster needs.
