Effectively using single node cluster

SRoy — Fri, 16 Sep 2022 10:16:47 GMT

Hi,

We are trying to do a PoC of an idea we have.

We are trying to leverage the cloudera single node cluster hosted on virtual box.

We need spark 1.6, HBase 1.2 and hive to run our PoC.

Where can I find the instructions on how to shutdown all but the required service via Cloudera Manager.

We are running into memory issues with so many services running.

Any pointers/help would be appreciated.

Thanks,

Roy

When you try to stop a service, it will warn you which services depend on
it if they are running. If you try to start a service, it will warn you
which services it depends on if they are not running.

I believe Zookeeper, HDFS, and YARN are the only other services you need to
run for Spark, HBase, and Hive.

I ended up increasing the memory on my iMac to 32GB.
