-----------------------------------

             Summary: SubStrStatEstimator.estimate throws NullPointerException
                 Key: HIVE-24839
                 URL: https://issues.apache.org/jira/browse/HIVE-24839
             Project: Hive
          Issue Type: Bug
            Reporter: Robbie Zhang
            Assignee: Robbie Zhang


This issue can be reproduced by running the following queries:
{code:java}
create table t0 (s string);
create table t1 (s string, i int);
insert into t0 select "abc";
insert into t1 select "abc", 4;
select substr(t0.s, t1.i-1) from t0 join t1 on t0.s=t1.s;
{code}
The select query fails with error:
{code:java}
Error: Error while compiling statement: FAILED: NullPointerException null (state=42000,code=40000)
{code}
