TO Shalom：
    Thank you for your reply too, sorry it is until now that I read this mail. >>>Do you have jdk 1.8 installed? >>>Is JAVA_HOME set in your cassandra-env.sh file?answer1: of course, 5 years ago, I have used command bin/cassandra to startup cassandraeven now I set  JAVA_HOME  in cassandra-env.sh by "export JAVA_HOME=/data2/programs/jdk1.8.0_202/", and the echo is correct, but the error is same. 
>>>Also, try to check the /var/log/cassandra/startup.log for additional information. 


answer2: new cassandra 's default log director is cassandra_home's subdirectory of log not the old one as you said. 
    And thanks Dimo, I will try your new method tomorrow. 

Sincerely yours,

Georgelin

Hi Georgelin, 

Do you have jdk 1.8 installed? 
Is JAVA_HOME set in your cassandra-env.sh file?Also, try to check the /var/log/cassandra/startup.log for additional information. 

Hope this helps.

To Dimo：
     Thank you for your reply and guiding , but not only my customized soure, but also the original cassandra 3.11.3/4 suddenly cann't run as several years ago and throw the -ea errors, and I have check the original running bin/cassandra source and centos's environment, no any -ea let. And the cassandra's running JVM's parameters are shown as below, there is no any -ea JVM variable left. I will check Centos JVM's environment, in addition to the suddenly deleted lib folder too, it seems that some hackers play a prank on me to stop my developing and using cassandra. 
      Is there any genius can help me? 

Sincerely yours,

Georgelin

-ea is a jvm parameter to enable assertions. Maybe you are passing it at the wrong place and the jvm interprets it as class name that you want to start.

Dear cassandra pioneers and users：	Yesterday afternoon, I can run cassandra 3.11.4's git-clone-src by using "bin/cassandra", but after I changed some codes by Eclipse, and compile without any error, not only the runnable source version, but also I redownload 3.11.4-bin.tar.gz and 3.11.3 from official website, they can't run by command of "./bin/cassandra", the steps and logs are as below:
