System Validation -Pre Install:
Test Case Expected Output
Disk Check All the disks should pass the test
Memory All the nodes should pass memory test
RPC Test All the nodes should pass RPC Test
Network Test All the nodes should pass network test
Cluster Audit Script All the nodes should report same configuration
CPU Test
Memory Check:
-sh-4.1$ free -m
total used free shared buffers cached
Mem: 96709 90716 5993 0 742 85233
-/+ buffers/cache: 4740 91968
Swap: 32767 420 32347
-sh-4.1$
Post Validation:
Test Case Expected Output
DFSIO Puts IO load on the cluster and completes successfully
TeraGen Puts load on the cluster and jobs run successfully
TeraSort Puts load on the cluster and jobs run successfully
Cloudera/MapR Audit
More Benchmarking
Hardware Failures:
Ensure that "No Interruption to services" when you perform below activity:
Power off Data Node –Pulling the Plug
Stop Network Interface for Data Node
Disk controller Failure for Data Node – Pull the hard disk out of the box.
Disk Controller Failure for CLDB Node – Pull the hard disk out of the box.
Disk Controller Failure for MySQL Node – Pull the hard disk out of the box.
Network Interface Failure for Hive Metastore Node
Power off Hive Metastore Node - – Pulling the Plug
Power off MySQL Node – Pulling the Plug
Power off entire RACK
Network Switch Failure – We need to engage Network team to figure out how to do this and if it is doable.

Memory Check:
The free
command allows you to display the amount of free and used memory on the system.
To do so, type the following at a shell prompt:
The free command
provides information about both the physical memory (Mem) and swap space
(Swap). It displays the total amount of memory (total), as well as the amount
of memory that is in use (used), free (free), shared (shared), in kernel
buffers (buffers), and cached (cached). For example:
total used free shared buffers cached
Mem: 96709 90716 5993 0 742 85233
-/+ buffers/cache: 4740 91968
Swap: 32767 420 32347
