daicheng updated IMPALA-12322:
------------------------------
Description:
impala version is 3.1.0-cdh6.1
i have set system timezone=Asia/Shanghai:
here is the bug:
*step 1*
i have parquet file with two columns like below,and read it with impala-shell
and spark (timezone=shanghai)
the result both exactly right。
*step two*
create kudu table with impala-shell:
CREATE TABLE default.test_{_}test{_}_test_time2 (id BIGINT,t TIMESTAMP,PRIMARY
KEY (id) ) STORED AS KUDU;
note: kudu version:1.8
and insert 2 row into the table with spark :
*stop 3*
read it with spark (timezone=shanghai)，spark read kudu table with kudu-client
api,here is the result:
the result is still exactly right。
but read it with impala-shell:
the result show late 8hour
*conclusion*
it seems like impala timezone didn't work when kudu column type is
timestamp, but it work fine in parquet file,I don't know why?
