Hi, I'm running a query like this:
CREATE TABLE foo STORED AS ORC AS SELECT id, season, amount, ntile(10) OVER ( PARTITION BY season ORDER BY amount DESC ) FROM bar; On a small enough dataset that works fine but when switching to a larger sample we're seeing exceptions like this: "Caused by: org.apache.hadoop.hive.ql.metadata.HiveException: Reset on PersistentByteBasedList not supported" Looking at the code (without really understanding it) we tried setting: SET hive.ptf.partition.persistence='org.apache.hadoop.hive.ql.exec.PTFPersistence$PartitionedByteBasedList'; because that List supports reset but we are seeing a ClassNotFoundException so we're doing that wrong. Next try was setting hive.ptf.partition.persistence.memsize higher which worked but first of all we don't really understand what all of that stuff is doing and second of all we fear that it just might break down again. Any hints as to what that error really means and how to deal with it would be greatly appreciated. Thanks! Lars
