    * "Call to unbound-fn" Error solved. To use functions within Cascalog…
    … queries, hadoop needed to call "require" on the containing namespace. If you define functions at the repl, the namespace file might not exist, and this call will fail; previously, Cascalog would squash these exceptions.
    This fix explicitly checks namespace existence, letting all others errors pass through. Anyone seeing an "unbound fn" exception will now see some far more enlightening exception about what's wrong with the namespace.
    * Anything that implements IFn can now be used as an op, provided it's bound to a var. For example, `(def is-bob? #{"bob"})` is now a valid predicate.
    * Vars can now be serialized as op parameters or constants. For example,
    ;; Vars as parameter args
    (defmapop var-apply [v]
       [& xs]
       (apply v xs))
    (fact?<- [[1 2 3]]
             [?x ?y ?z]
             ([[1 2]] ?x ?y)
             (var-apply [#'+] ?x ?y :> ?z))
    ;; Vars as constants
    (def coll-src
        [[[3 2 4 1]]
         [[1 2 3 4 5]]])
    (fact?<- [[10] [15]]
             (coll-src ?coll)
             (reduce #'+ ?coll :> ?sum))
    * Added explicit Kryo serialization for `java.util.regex.Pattern`.
    * Kryo serialization now captures objects without default constructors.
    * MemorySourceTap (and data structures) now use Hadoop's serialization mechanisms, vs defaulting to Kryo.
  • 1.8.5

    * Moved project configurations over to cascalog.
    * Memory-Source-Tap now uses project settings from job-conf.clj (bugfix!)
    * Kryo Serialization for clojure primitives, clojure collections and select java primitives.
    * Functions defined with defmain are now callable by their supplied names. (Previously they weren't usable except to generate aot-compiled classes.)
    * `bootstrap` and `bootstrap-emacs` are now functions, not macros.
    * defops and defmain include :skip-wiki true in metadata, allowing them to be used with codox or autodoc and not generate clutter.
    * Sets are no longer destructured as tuples by Cascalog.
    In addition to previous support for the various number types + strings, the following classes are now serialized by default:
    - **Java primitives & Collections**
      - java.math.BigDecimal
      - java.math.BigInteger
      - java.util.Date
      - java.util.UUID
      - java.sql.Date
      - java.sql.Time
      - java.sql.Timestamp
      - java.util.ArrayList
      - java.util.HashMap
      - java.util.HashSet
    - **Clojure Primitives**
      - clojure.lang.Keyword
      - clojure.lang.Symbol
      - clojure.lang.Ratio
      - clojure.lang.Var
      - clojure.lang.BigInt (only in Clojure 1.3)
    - **Clojure Collections and sequences:**
      - clojure.lang.Cons
      - clojure.lang.IteratorSeq
      - clojure.lang.LazySeq
      - clojure.lang.ArraySeq
      - clojure.lang.MapEntry
      - clojure.lang.PersistentArrayMap
      - clojure.lang.PersistentHashMap
      - clojure.lang.PersistentHashSet
      - clojure.lang.PersistentList
      - clojure.lang.PersistentList$EmptyList
      - clojure.lang.PersistentStructMap
      - clojure.lang.PersistentVector
      - clojure.lang.StringSeq
  • 1.8.4

    * Add project-wide jobconf settings in job-conf.clj.
    * optional docstring and metadata support on defparallelagg and defparallelbuf.
    * def*ops now present proper argument list metadata.
    * Added cascalog.ops/partial
    * fixed :sinkmode op
    * defaggregateop no longer fails when returning nil
    * Better error reporting on parametrized ops (variadic args aren't supported; this now throws an error.)
