I have created a HBase by mentioning the default versions as 5
create 'tablename',{NAME => 'cf', VERSIONS => 5} and inserted two rows(row1 and row2)
put 'tablename','row1','cf:id','row1id'
put 'tablename','row1','cf:name','row1name'
put 'tablename','row2','cf:id','row2id'
put 'tablename','row2','cf:name','row2name'
put 'tablename','row2','cf:name','row2nameupdate'
put 'tablename','row2','cf:name','row2nameupdateagain'
Tried to select the data by using scan and I'm getting the latest updated data. and when I tried to select the different versions data by using the below command I got the different versions data.
scan 'tablename',{RAW => true, VERSIONS => 5}
Now created a Hive External table to point to this HBase table
CREATE EXTERNAL TABLE hive_timestampupdate(key int, value string)
STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'
WITH SERDEPROPERTIES ("hbase.columns.mapping" = ":key,cf:name")
TBLPROPERTIES ("hbase.table.name" = "tablename");
select * from hive_timestampupdate
When I queried the table hive_timestampupdate, I'm able to see the data.
By default here I'm getting the latest updated data based on timestamp. Here also I want to query the data of different versions.
Hive command that will fetch the different versions data of HBase.
Any help please.
Thanks in Advance.
