> 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

>  
> 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}
>  
> The same behaviour exists when we use any other built-in functions or UDFs.
