Elena Stepanova added a comment - 2013-04-24 17:49 I'm getting the same error when I'm trying to install Cassandra for the second time , e.g. install - uninstall - install.

Sergei Petrunia added a comment - 2013-05-02 05:54 It's difficult for me to recollect the exact circumstances I got the error the first time. I've now tried with 10.0.2, on the same Fedora 16 machine. I now used binary tarball mariadb-10.0.2-linux-x86_64.tar.gz, 87d368cd292a90882cdfadc1a31110e6. I observe the same problem as you - first plugin installation succeeds, but if I uninstall/and then install back, I get an error: MariaDB [test] > install plugin cassandra soname 'ha_cassandra.so'; Query OK, 0 rows affected (0.01 sec) MariaDB [test] > show plugins; --------------------------- -------- ------------------ --------------- -------- Name Status Type Library License --------------------------- -------- ------------------ --------------- -------- binlog ACTIVE STORAGE ENGINE NULL GPL ...

Sergei Petrunia added a comment - 2013-05-02 05:56 I think, when INSTALL PLUGIN works for the first time but not for the second - it looks like a bug in plugin system.
