Work Description: rtrivedi12 opened a new pull request, #4159:
URL: https://github.com/apache/hive/pull/4159
…nged FQN for JsonSerDe in HMS DB
HIVE-18545 makes Hcatalog JsonSerde use the "hive.serde2" version as a back
end, there are no feature differences between these implementations. This
change will fix tests to use the new JsonSerDe class and remove JsonSerDe from
hive-contrib. Hive Upgrade schema script should automatically update the hive
table schema to rename the serde package.
### What changes were proposed in this pull request?
1. Fixed tests to use new SerDe class
'org.apache.hadoop.hive.serde2.JsonSerDe'
2. Removed JsonSerDe from hive-hcatalog.
3. Schema upgrade scripts update the SLIB column value in SERDES table to
update it from "org.apache.hive.hcatalog.data.JsonSerDe" to
"org.apache.hadoop.hive.serde2.JsonSerDe"
### Why are the changes needed?
Removing redundant code to make JsonSerde as first class serde in hive
Better user experience after the upgrade (Avoids CNF)
### Does this PR introduce _any_ user-facing change?
'No'
### How was this patch tested?
mvn test -Dtest=TestMiniLlapLocalCliDriver
-Dqfile=json_serde1.q,json_serde_qualified_types.q,json_serde_tsformat.q,parquet_mixed_partition_formats2.q,temp_table_parquet_mixed_partition_formats2.q
