Thanks Dudu, looks like both of them pointing to same class. Let me
check if there is any problem with data which is not visible and
surprising LCASE is resolving issue but not lower.

Hi
According to documentation LCASE is a synonym for LOWER.
From what I've seen in the source code, it seems right.
https://github.com/apache/hive/blob/f089f2e64241592ecf8144d044bec8a0659ff422/ql/src/java/org/apache/hadoop/hive/ql/exec/FunctionRegistry.java
system.registerGenericUDF("lower", GenericUDFLower.class);
system.registerGenericUDF("lcase", GenericUDFLower.class);
Please verify that you've run the exact same queries.
If you still see an issue, please share the relevant DDL (table/tables
definition) and a small subset of data so I would be able to reproduce it.
Thanks
Dudu

Subject: Any difference between LOWER and LCASE
Hi Team,
Is there any difference between LOWER and LCASE functions in Hive. For one of
the query, when we are using LOWER in where condition, it is failing to match
record. When we changed to LCASE, it started matching.
I surprised to see differences in LOWER and LCASE. Can any one know why there 2
function for same functionality. Is there any thing to do with any special or
Unicode characters where Lower and LCASE differs in functionality
