Ramakrishna S updated CARBONDATA-1763:
--------------------------------------
Description:
Steps:
1. Create table and load with data
2. Run update query on the table - this will take table metalock
3. In parallel run the pre-aggregate table create step - this will not be
allowed due to table lock
4. Rerun pre-aggegate table create step
*+Expected:+* Pre-aggregate table should be created
*+Actual:+* Pre-aggregate table creation fails

Steps:
1. Create table and load with large data
create table if not exists lineitem4(L_SHIPDATE string,L_SHIPMODE
string,L_SHIPINSTRUCT string,L_RETURNFLAG string,L_RECEIPTDATE
string,L_ORDERKEY string,L_PARTKEY string,L_SUPPKEY string,L_LINENUMBER

load data inpath "hdfs://hacluster/user/test/lineitem.tbl.1" into table
lineitem4
options('DELIMITER'='|','FILEHEADER'='L_ORDERKEY,L_PARTKEY,L_SUPPKEY,L_LINENUMBER,L_QUANTITY,L_EXTENDEDPRICE,L_DISCOUNT,L_TAX,L_RETURNFLAG,L_LINESTATUS,L_SHIPDATE,L_COMMITDATE,L_RECEIPTDATE,L_SHIPINSTRUCT,L_SHIPMODE,L_COMMENT');
2. Create a pre-aggregate table
create datamap agr_lineitem4 ON TABLE lineitem4 USING
"org.apache.carbondata.datamap.AggregateDataMapHandler" as select
L_RETURNFLAG,L_LINESTATUS,sum(L_QUANTITY),sum(L_EXTENDEDPRICE) from lineitem4
group by L_RETURNFLAG, L_LINESTATUS;
3. Run aggregate query at the same time
select l_returnflag,l_linestatus,sum(l_quantity),sum(l_extendedprice) from
lineitem4 group by l_returnflag, l_linestatus;
*+Expected:+*: aggregate query should fetch data either from main table or
pre-aggregate table.
*+Actual:+* aggregate query does not return data until the pre-aggregate table
is created
