问题
1，创建带分区
CREATE TABLE hbase_table_2(key int, value string) PARTITIONED BY (date String) ROW FORMAT DELIMITED FIELDS TERMINATED BY '\t' STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler' WITH SERDEPROPERTIES ("hbase.columns.mapping" = ":key,cf1:val") TBLPROPERTIES ("hbase.table.name" = "xyz2");(1) , insert into hbase_table_2 partition (date) select body_bytes_sent,remotea_ddr,date from access_log limit 10;
不报错 ，但表没数据
(2)，insert into hbase_table_2 partition (date =‘201212’) select body_bytes_sent,remotea_ddr from access_log limit 10;
有数据，hbase 没分区date 数据
(3)，插入xyz2 put ‘xyz2’, 123, ‘cf1:val’, ‘1.1.1.1’ 对hive 所有分区都有这条数据了
实例 ，2种情况
