Chetan Bhat created CARBONDATA-1869:
---------------------------------------
Summary: Null pointer exception thrown when concurrent load and
select queries executed for table with dictionary exclude or NO_INVERTED_INDEX
Key: CARBONDATA-1869
URL: https://issues.apache.org/jira/browse/CARBONDATA-1869
Project: CarbonData
Issue Type: Bug
Components: data-load
Affects Versions: 1.3.0
Environment: 3 node ant cluster
Reporter: Chetan Bhat
Steps -
>From beeline terminal a table is created with with table properties having
>dictionary exclude or NO_INVERTED_INDEX-
create table test(a1 int) STORED BY 'org.apache.carbondata.format'
TBLPROPERTIES ('DICTIONARY_EXCLUDE'='a1'); or
create table test(a1 int) STORED BY 'org.apache.carbondata.format'
TBLPROPERTIES ('NO_INVERTED_INDEX'='a1');
From 3 concurrent beeline terminals the below sequence of insert into select
and select queries are executed 120 times.
insert into test select 2147483647;
select * from test;
select count(*) from test;
select a1 from test;
select
round(a1),bround(a1),floor(a1),ceil(a1),rand(),exp(a1),ln(a1),log10(a1),log2(1),log(a1),pow(a1,a1),sqrt(a1),bin(a1),pmod(a1,a1),sin(a1),asin(a1),cos(a1),tan(a1),atan(a1),degrees(a1),radians(a1),positive(a1),negative(a1),sign(a1),factorial(a1),cbrt(a1)
from test;
【Expected Output】：The insert into select query should be successful and the
null pointer exception should not be thrown when concurrent load and select
queries executed for table with dictionary exclude or NO_INVERTED_INDEX.
【Actual Output】：Null pointer exception thrown when concurrent load and select
queries executed with table properties having dictionary exclude or
NO_INVERTED_INDEX
