{code}
In my conf/cassandra-env.sh I have:
{code}
# Configure the following for JEMallocAllocator and if jemalloc is not
available in the system
# library path (Example: /usr/local/lib/). Usually "make install" will do the
right thing.
export LD_LIBRARY_PATH=/usr/local/lib
JVM_OPTS="$JVM_OPTS -Djava.library.path=/usr/local/lib/"
{code}
I believe this file is not sourced by the tools, this is why a tool that might
need that library cannot find it.
