allow using nodes option for stress #608

Closed XN137 closed 7 years ago

XN137 commented 7 years ago

it was not possible to give a custom nodes parameter to stress, because all live nodes are added all the time.

before:

→ ccm status test1                                           
Cluster: 'test1'
----------------
node1: UP
node3: UP
node2: UP

# chris in ~/code/ccm on git:master ✖︎ [9:21:54]
→ ccm stress write n=1000 -node whitelist 127.0.0.1,127.0.0.2
-node is defined multiple times. Each option/command can be specified at most once.
Usage:      cassandra-stress <command> [options]
Help usage: cassandra-stress help <command>
...

after this PR it is possible:

# chris in ~/code/ccm on git:stress-nodes-options ✖︎ [9:19:20]
→ ccm status test1

----------------

additionally before the stress cmd always exited with return code 0:

→ ccm stress write foo=1000; echo $?
Invalid parameter foo=1000
Usage:      cassandra-stress <command> [options]
Help usage: cassandra-stress help <command>
...
-tokenrange           : Token range settings
0

now it will correctly indicate an error:

→ ccm stress write foo=1000; echo $? 
Invalid parameter foo=1000
Usage:      cassandra-stress <command> [options]
Help usage: cassandra-stress help <command>
...
