--------------------------------------
Summary: Misalignment in matching db name from Hive and Webhcat
Key: HIVE-24557
URL: https://issues.apache.org/jira/browse/HIVE-24557
Project: Hive
Issue Type: Bug
Components: WebHCat
Affects Versions: 2.3.6
Reporter: Davide Vergari
I found a small misalignment on how Hive and WebHCat parse database name
starting with numbers.
If you execute:
{quote}hive> create database 2020db;
OK
Time taken: 0.44 seconds
hive>
{quote}
it works, but if you do the same on webhcatalog it doesn't:
{quote}curl -i -s -X PUT -HContent-type:application/json -d '\{"comment":
"Test", "location":
"hdfs://singlenode.localdomain:8020/apps/hive/warehouse/2020db"}'
'http://singlenode.localdomain:50111/templeton/v1/ddl/database/2020db?user.name=hdfs'

I suggest to harmonize the behavior, maybe applying a patch like the following
one:
