Bala Divvela created HIVE-13317:
-----------------------------------
Summary: HCatalog unable to read changed column structure
Key: HIVE-13317
URL: https://issues.apache.org/jira/browse/HIVE-13317
Project: Hive
Issue Type: Bug
Components: Hive
Reporter: Bala Divvela
Priority: Minor
I have a table t1 which has a single column of datatype array of struct like
`a_details array<struct<a1:string,id:string,number:string>>`. It has few
records for partition up=1 which can be read from both Hive and Pig(via
HCatalog) properly.
Now i need a requirement of adding one more sub column in a_details struct. new
structure would be
`a_details array<struct<a1:string,id:string,number:string,gender:string>>`.
After the column change few more records have been appended in one more
partition ups=2.
Now i am able to read only up=2 partitions data from Pig(HCatalog).
When i try to load up=1 data from t1 table using Pig HCatalog it throws an
exception "ERROR converting read value to tuple".
FYI, I can read all the data from hive properly, it throws exception only when
i load from pig using HCatalog.
Please help me in resolving this.
