spark git commit: [SPARK-4203][SQL] Partition directories in random
order when inserting into hive table
Repository: spark

[SPARK-4203][SQL] Partition directories in random order when inserting into hive table
When doing an insert into hive table with partitions the folders written to the file system are in a random order instead of the order defined in table creation. Seems that the loadPartition method in Hive.java has a Map<String,String> parameter but expects to be called with a map that has a defined ordering such as LinkedHashMap. Working on a test but having intillij problems
