Cassandra-stress混合压测报错：无效参数问题排查请求

Let's break down what's causing that frustrating "Invalid parameter us..." error in your cassandra-stress command—it's a tiny syntax slip-up that's easy to fix.

The error is directly pointing to the user profile=./cassandra.yaml segment of your command. Cassandra-stress has no user profile parameter; you've accidentally added an extra, unnecessary user keyword here. The correct way to specify a custom workload profile is simply profile=./cassandra.yaml.

Here's your corrected command with that extra user removed (all other valid parameters are preserved):

~/cassandra-stress mixed ratio(write=5,read=1) n=100000 profile=./cassandra.yaml duration=15m 'ops(insert=10)' cl=QUORUM -rate threads=100 -mode native cql3 port=9042 user=cassandra password=cassandra -transport truststore=/home/../../truststore.jks truststore-password="*********" keystore=/home/../../../cassandra-keystore.jks keystore-password="*******" ssl-protocol=****** ssl-alg=******* ssl-ciphers=************* -node $NODES -port native=9042 jmx=7199

A couple quick follow-up checks to ensure everything runs smoothly:

• Verify that your cassandra.yaml profile file exists at the specified path and uses valid cassandra-stress syntax (it should properly define your target schema and operations).
• Note that your authentication username is already correctly set later in the command with user=cassandra, so there's no need to repeat any user-related flags before the profile parameter.
