What About Cluster Creation Failer

[Oula Alshiekh]

first of all you mentioned in the page
https://help.syncfusion.com/bigdata/cluster-manager/cluster-creation
Step 9: Once validation is successful, click Next to start cluster provisioning.

the validation of my cluster was successful but cluster provisioning. was not
in the attachment you will find the picture which is divided because of vmware un ability to edit settings

what is my problem ? i cant know should i have abig experience in hadoop first to know what should i do ?
note in this link https://www.syncfusion.com/forums/127068/cluster-creation-overwrite
you adviced me to extend name node ram to 8 Gb and others to 4
but my device whole ram is only 12 Gb
so i made three vms namenode 192.168.88.185 4 Gb ,
secondary node 192.168.88.181 2 Gb
Datanode 192.168.88.182 2 GB
and 2 gb for my device ,every think works slow
that are all the possibilities i have could this be the reason of cluster creation failer


the alarm gave me these three messages if they are helpful

Hi Oula,

 

We regret for the inconvenience caused.

 

As I mentioned in the another thread, the below RAM requirement is mandatory to get work all Hadoop and ecosystem services properly.

 

RAM requirement for multi node creation:

For name nodes: 8 GB or higher  

For data nodes: 4 GB or higher  

 

 

We suggest you to use separate physical machines to meet multi node cluster creation's hardware requirement or you can try to create development cluster in a single node (no multiple VM split in same machine is not needed).

 

Please refer the following link to create pseudo node cluster in single node,
