Newbie, services not started in Cloudera Quickstart

[ Edited ]
I just installed Cloudera quickstart vm 5.12.0

 

I launched Cloudera Express from the Desktop

I can see Cloudera Manager but the servcies seemed stopped

 

I had one system health warning about "quickstart.cloudera" / "Clock Offset"

I tried to "Restart" all services. Got the message that all services started successfully.

 

Unfortunately, within a few seconds, all services show a red icon and I now have 4 health warnings...

 

  • HBase / HBase Master Health
  • HDFS / Namenode Health
  • YARN (MR2 included) / ResourceManager Health
  • quickstart Cloudera / Clock Offset

I am obvioulsy doing something wrong... but what?

 

Any idea?

 

Thanks

Re: Newbie, services not started in Cloudera Quickstart

Hello,

 

First make sure you configure the VM with a minimun of 8GB of RAM and 2 CPU cores.

 

Second, don't try to start all services. Start only the services you really need. In getting started page (http://quickstart.cloudera/#/tutorial/getting_started) you only need to start 5 services.

 

If you still have the same problem copy&paste here the health warning in order we can help you.

 

I had this problem some days ago, and I fixed it by stopping all services and starting only the ones I need to do the exercice. It this doesn't work try restarting the VM (Linux).

 

Regards

I'd love to start some service... but everything seems to fail right now...

 

Tried to add an image below but I suspect it's no good...

Please use the link otherwise

 

All services failing

One failure on the Hosts seems to be 

Process Status (

Cloudera Management Service Host Monitor quickstart

)
Feb 19, 9:54 AM PST

Test of whether the process state of this role is as expected.
Loading... This role's host has been out of contact with Cloudera Manager for too long.

Re: Newbie, services not started in Cloudera Quickstart

I have tried to restart the machine and it looks better.

 

It looks like I allocated too much memory... which does not surprise me.

 

"quickstart.cloudera: Memory Overcommit Validation Threshold Suppress...
Memory on host quickstart.cloudera is overcommitted. The total memory allocation is 13.6 GiB bytes but there are only 7.7 GiB bytes of RAM (1.5 GiB bytes of which are reserved for the system). Visit the Resources tab on the Host page for allocation details. Reconfigure the roles on the host to lower the overall memory allocation. Note: Java maximum heap sizes are multiplied by 1.3 to approximate JVM overhead.

How would I get in lowering memory usage?"

 

I am quite happy to stop services I might have started by mistake...
