> h2. STEP 1. Create and upload test data
> Execute in command line:
> {noformat}
> nano stest.data
> {noformat}
> Add to file:
> {noformat}
> 000126,000777
> 000126,000778
> 000126,000779
> 000474,000888

> hadoop fs -put stest.data /
> {noformat}
> {noformat}
> hive> create table stest(x STRING, y STRING) ROW FORMAT DELIMITED FIELDS
> TERMINATED BY ',';
> hive> LOAD DATA INPATH '/stest.data' OVERWRITE INTO TABLE stest;
> {noformat}
> h2. STEP 2. Execute test query (with cast for x)
> {noformat}
> select x from stest where cast(x as int) = 126;
> {noformat}
> EXPECTED RESULT:
> {noformat}
> 000126
> 000126
> 000126
> {noformat}
> ACTUAL RESULT:
> {noformat}
> 126
> 126
> 126
> {noformat}
> h2. STEP 3. Execute test query (no cast for x)
> {noformat}
> hive> select x from stest where x = 126;
> {noformat}
> EXPECTED RESULT:
> {noformat}
> 000126
> 000126
> 000126
> {noformat}
> ACTUAL RESULT:
> {noformat}
> 126
> 126
> 126
> {noformat}
> In steps #2, #3 I expected '000126' because the origin type of x is STRING in
> stest table.
> Note, setting hive.optimize.constant.propagation=false fixes the issue.
> {noformat}
> hive> set hive.optimize.constant.propagation=false;
> hive> select x from stest where x = 126;
> OK
> 000126
