Hey all,
I'm on Hive 0.10.0 on one of my clusters. We had a namenode hostname
change, so I'm trying to point all of our tables, partitions and databases
to the new locations.
When i describe database mydb, the location shows up as
hdfs://old_hostname/user/hive/warehouse/mydb.db, and i want to

Hi there,
I'm trying to pass some external properties to a UDF. In the MapReduce
world I'm used to extending Configured in my classes, but in my UDF class
when initializing a new Configuration object or HiveConf object it doesn't

aren’t splittable, so they get assigned to one mapper.

Hey all,
Just wondering what the best way is to rename specific Hive table
partitions. Is there some HiveQL command for this, or will I need to insert
into new partitions to reflect the new naming convention?
Cheers,
