Subject Cassandra start Warning
Date Sat, 23 Jan 2016 09:30:15 GMT

My version is 3.2.1, when starting Cassandra, I found 3 warning in log:

W1) WARN  09:19:24 jemalloc shared library could not be preloaded to speed
up memory allocations

W2) WARN  09:19:24 JMX is not enabled to receive remote connections. Please
see for more info.

W3) WARN  09:19:24 Cassandra server running in degraded mode. Is swap
disabled? : false,  Address space adequate? : true,  nofile limit adequate?
: false, nproc limit adequate? : false

Any ideas to resolve them?
