-----------------------------------------
Summary: HiveParser is misinterpreting quotes in from/to string of
translate function
Key: HIVE-22963
URL: https://issues.apache.org/jira/browse/HIVE-22963
Project: Hive
Issue Type: Bug
Components: Parser
Reporter: Ganesha Shreedhara
Parsing of query fails when we use single or double quotes in from/to string of
translate function in 2.3*/3.1.1 version of hive. Parsing of the same query is
successful in 2.1.1 version of hive.
*Steps to reproduce:*
{code:java}
CREATE TABLE test_table (data string);
INSERT INTO test_table VALUES("d\"a\"t\"a");
select translate(data, '"', '') from test_table;
{code}
Parsing fails with the following exception:
{code:java}
NoViableAltException(355@[157:5: ( ( Identifier LPAREN )=>
partitionedTableFunction | tableSource | subQuerySource | virtualTableSource
)])NoViableAltException(355@[157:5: ( ( Identifier LPAREN )=>

Parsing is successful when double quote is escaped.
The following query works:
{code:java}
SELECT translate(data, '\"', ' ') from test_table;
{code}
But the behaviour which looks buggy is when the double quote is not escaped in
from/to string of translate function, it seems to be interpreting the double
quote in from/to string of next translate function as ending quote.
Parsing is successful for the following queries.
{code:java}
select translate(data, '"', ''), translate(data, '"', '') from test_table;
select translate(data, '"', ''), translate(data, ' ', '"') from test_table;
select translate(data, "'", ""), translate(data, "'", "") from test_table;
select translate(data, "'", ""), translate(data, " ", "'") from test_table;
select translate(data, '"', '"') from test_table;
select translate(data, "'", "'") from test_table;
{code}
