[jira] [Created] (HIVE-5592) Add an option to convert enum as struct as of Hive 0.8

Jie Li created HIVE-5592:


 Summary: Add an option to convert enum as struct as of 
Hive 0.8
 Key: HIVE-5592
 URL: https://issues.apache.org/jira/browse/HIVE-5592
 Project: Hive
  Issue Type: Bug
Affects Versions: 0.11.0, 0.10.0, 0.12.0
Reporter: Jie Li


HIVE-3222 introduced the incompatible change: Hive handling of enum types has 
been changed to always return the string value rather than struct. 
But it didn't add the option "hive.data.convert.enum.to.string"  as planned and 
thus broke all Enum usage prior to 0.10.

Hi, we used to use the struct representation in Hive 0.8 and got hit 
by this incompatible change after upgrading. Any reason not providing a 
configuration for this change? I guess it might break some other users.

[jira] [Commented] (HIVE-2227) Remove ProgressCounter enum in Operator

Even though this ticket has not been committed, the current counterNameToEnum 
is not initialized and remains null. This prevents the operator counters 
(NUM_INPUT_ROWS NUM_OUTPUT_ROWS TIME_TAKEN) to be recorded. Any thoughts on 
what was broken?
