CM managing multiple different CDH Cluster
How do we install multiple version of CDH from Cluster?
when we install CM is only defaulted to 1 CDH version. Do we need to add a custom parcel for specific CDH?
Cloudera Manager Warning
I see a few warning like below. Can we ignore this for lab purpoess?
Memory on host hadoop7.expecc.com is overcommitted. The total memory allocation is 13.2 GiB bytes but there are only 15.6 GiB bytes of RAM (3.1 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.
