Hi, May I know how to use the functions mentioned in http://spark.apache.org/docs/1.4.0/api/scala/index.html#org.apache.spark.sql.functions$ in spark sql?
when I use like "Select last(column) from tablename" I am getting error like 15/07/27 03:00:00 INFO exec.FunctionRegistry: Unable to lookup UDF in metastore: org.apache.hadoop.hive.ql.metadata.HiveException: MetaException(message:NoSuchO bjectException(message:Function default.last does not exist)) java.lang.RuntimeException: Couldn't find function last Thanks, Vinod
