> Use impala 2.0 to connect to hive-0.13 Metastore.
> From impala, run the following queries:
> {noformat}
> create table voter1(voter_id int,name string,age tinyint, registration
> string,contributions decimal(5,2),voterzone smallint,create_time timestamp)
> row
> format delimited fields terminated by '\t';
> load data inpath '/tmp/votertab' into table voter1;
> {noformat}
> After this, can successfully select from table voter 1.
> Execute the following from impala shell:
> {noformat}
> > compute stats voter1;
> {noformat}
> After this, got the following error selecting from table voter1:
> {noformat}
> > select * from voter1 limit 5;
> Query: select * from voter1 limit 5
