      Low

      Description

      If the commit log directory has no free space, Cassandra hangs on startup.

      The main thread is waiting:

      "main" prio=9 tid=0x00007fefe400f800 nid=0x1303 waiting on condition [0x000000010b9c1000]

      	at org.apache.cassandra.service.CassandraDaemon.main(CassandraDaemon.java:585)
      

      but COMMIT-LOG-ALLOCATOR is RUNNABLE:

      "COMMIT-LOG-ALLOCATOR" prio=9 tid=0x00007fefe5402800 nid=0x7513 in Object.wait() [0x0000000118252000]

      	at org.apache.cassandra.utils.WrappedRunnable.run(WrappedRunnable.java:28)
      	at java.lang.Thread.run(Thread.java:745)
      

      but making no progress.

      This behaviour has changed since 1.2 (see CASSANDRA-5737).
