Alter the schema of Hive table

Question

I want to alter the table created in Hive which is mapped to HBase fields. Recently i have included few more column into HBase and thus would lik to add those fields into Hive as well.

for creation i used:

 CREATE EXTERNAL TABLE test1(rowKey STRING,a STRING,b STRING) 
 STORED BY  'org.apache.hadoop.hive.hbase.HBaseStorageHandler' WITH SERDEPROPERTIES 
 ('hbase.columns.mapping' = ':key,cf:address,cf:name') 
 TBLPROPERTIES ('hbase.table.name' = 'test');

now i want to add one more column in hive tables test1 which should be mapped to hbase but i don't find any way to do this. Pleas help Thanks.

Answer 1

Because you use external table, the easiest way is drop and create it again.

drop table test1;

and

create external table test1 {...};
