      Description

      We've seen several instances of these mystery deadlocks in impalad's embedded JVM. The signature is a deadlock stemming from sun.security.provider.Sun being locked by an unknown owner.

      Found one Java-level deadlock:
      =============================
      "Thread-24":
        waiting to lock monitor 0x0000000012364688 (object 0x000000008027ef30, a sun.security.provider.Sun),
        which is held by UNKNOWN_owner_addr=0x0000000014120800
      

      If this happens in HDFS, it causes HDFS I/O to hang and queries to get stuck. If it happens in the Kudu client it also causes hangs.
