Hi,
I build the hive table mapped with hbase table,
CREATE TABLE http_access(key string, client_ip string, client_port int,
request_method string, event_time timestamp)
STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'
WITH SERDEPROPERTIES (
"hbase.columns.mapping" =
":key,client:ip,client:port,request:method,request:event_time"
);
The data is store with hbase client.
I get an issue while query with hive for (hbase/hive integration), while I
execute sql: select ip, port, request_method from http_access, it works well
with no problem,
but while I execute below sql: select ip, port, event_time from http_access, I
got below exception.
The only difference between two sqls is: the event_time is timestamp type, I
can scan the corresponding hbase table and see the value of event_time is:
1338365792142 column=request:event_time,
timestamp=1338365739818, value=Wed May 30 16:15:06 CST 2012
Anyone who know what the issue is? (Not sure if I made a wrong mapping or
should I just store the timestamp value as long in hbase? currently I store the
value as java.util.Date)
Thank you very much....
Regards,
Peyton
