我在下面的第 5 步中遇到错误...非常感谢任何帮助。
我正在遵循https://cwiki.apache.org/Hive/hbaseintegration.html中给出的步骤
步骤1
hive> CREATE TABLE tblHbase(key int, a int, b int,c bigint)
STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'
WITH SERDEPROPERTIES ("hbase.columns.mapping" = ":key,f:a,f:b,f:c")
TBLPROPERTIES("hbase.table.name"="tblHbase");
第2步
hbase(main):001:0> describe "tblHbase"
DESCRIPTION ENABLED
{NAME => 'tblHbase', FAMILIES => [{NAME => 'f', B true
LOOMFILTER => 'NONE', REPLICATION_SCOPE => '0', V
ERSIONS => '3', COMPRESSION => 'NONE', MIN_VERSIO
NS => '0', TTL => '2147483647', BLOCKSIZE => '655
36', IN_MEMORY => 'false', BLOCKCACHE => 'true'}]
}
步骤#3
hive> describe tblhive;
OK id int a int b int c bigint
第4步
hive> select * from tblhive;
正常 1 101 102 103 2 201 202 203
Step#5 -- 从 Hive 向 HBase 表插入数据时出错
hive> insert overwrite table tblHbase select id,a,b,c from tblhive;
