Subject Re: Cassandra as in-memory cache
Date Sun, 11 Sep 2011 19:14:24 GMT
Hi, all.

I´m new at this and haven´t been able to install cassandra in debian
6. After uncompressing the tar and creating var/log and var/lib
directories, the command bin/cassandra -f results in message "exec:
357 -ea not found" preventing cassandra from run the process README
file says it is suppose to start.

Any help would be very appreciated.
