-------------------------------------------

             Summary: Silent startup failure with filesystem that does not support mmap
                 Key: CASSANDRA-9635
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-9635
             Project: Cassandra
          Issue Type: Bug
          Components: Core
            Reporter: Kevin McLaughlin
         Attachments: c_tdump.txt


C* version 2.0.9.

When running C* in virtualbox on OS X via boot2docker with the data directory on a shared volume from the host system (vboxfs), C* fails to start without printing any errors.

I do not know if C* is supposed to support filesystems that do not support mmap (does not appear so), however, I think the failure exposes a static initialization deadlock (http://ternarysearch.blogspot.ru/2013/07/static-initialization-deadlock.html).

I believe the virtualbox "bug" is https://www.virtualbox.org/ticket/819.

Stacktrace of the deadlock is attached.  When placing a t.printStackTrace() between lines 115 and 116 in https://github.com/apache/cassandra/blob/cassandra-2.0.9/src/java/org/apache/cassandra/db/commitlog/CommitLogAllocator.java, the stack trace at startup is:
