> impala version is 3.1.0-cdh6.1
> !35xwYkMIeefwOgMhhBBCCLlXbreIQAghhBBCCCGEkIfivwA62bfllMcqSwAAAABJRU5ErkJggg==|width=451,height=117!
> i have set system timezone=Asia/Shanghai:
> !AQFTDOCuJy6yAAAAAElFTkSuQmCC|width=548,height=131!
> 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)
> !4LWincd dPO98AAAAASUVORK5CYII=|width=606,height=214!
> !pB4HeSMXP4HxPSrGV0Hq0QAAAAASUVORK5CYII=|width=455,height=186!
> 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 :
> !AkLbNoZZQ2JEAAAAAElFTkSuQmCC|width=454,height=144!
> *stop 3*
> read it with spark (timezone=shanghai)，spark read kudu with kudu-client
> api,here is the result:
> !w9CIosotYzYIwAAAABJRU5ErkJggg==|width=543,height=186!
> the result is still exactly right。
> but read it with impala-shell:
> !fQAAAABJRU5ErkJggg==|width=629,height=101!
> 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?
