Ambari runs very slow

drenusha_gjurka — Tue, 07 Mar 2017 20:44:25 GMT

I am a begineer to Hadoop and im taking Hortonworks Sandbox tutorials . Ambari server runs so slow , hive , pig , every job every service , it loads and run very very slow , example if i run a simple select query of 10 rows , it takes tike to execute . My question is : is it okay with this , or do i have to install specific tools for different tasks ,like i`ve seen a tutorial when it is saying that qyering with beeline tool is faster , or do i have to execute everything with Putty , or to continue working in Ambari server http://localhost:8080/ . I appriciate every explanation . Thanks for time .

How much free memory do you have remaining in your Sandbox VM?

Can you increase the RAM and then try.

Linux commands:

To check memory

# free -m

To check if CPU resources are enough

# top

Else try to stop unwanted services that are running on your sandbox to free some resources.
