Problem

Something changed and now Cassandra will not start up. With the following errors seen in CASSANDRA_INSTALL_DIR/logs system.log or debug.log:

Alternate error seen on more recent Cassandra versions:

ERROR [main] NativeLibraryLinux.java:64 - Failed to link the C library against JNA. Native methods will be unavailable.
java.lang.UnsatisfiedLinkError: /tmp/jna-[generated filename].tmp: /tmp/jna-[generated filename].tmp: failed to map segment from shared object  
   at java.lang.ClassLoader$NativeLibrary.load(Native Method)

Resolution

7.7 docs mention of NOEXEC can be found here:

https://docs.axway.com/bundle/axway-open-docs/page...


Older answer:
The system was somehow updated to add NOEXEC permissions to the system temp directory. Pre 7.6.2, API GW and Cassandra require temp to be mounted with EXEC privileges, see pre-requisites in your Installation guide.

Solutions:

• Pre 7.6.2, please re-mount temp directory with EXEC privileges.
• Starting with 7.6.2, please see 7.6.2 Installation guide, sections: Additional prerequisites \ Post-installation
  [...]
  2. If you installed Cassandra during API Gateway installation,
  edit the file CASSANDRA_INSTALL_DIR/conf/cassandra-env.sh and add the following line:
  JVM_OPTS="$JVM_OPTS -Djava.io.tmpdir=<TheNewTmpDir>"
