Re: HBase table map to hive
If your schema is changing frequently I think it's better to use Avro for schema evolution, and go with 'Avro Serde' with 'AvroContainerInputFormat' & 'AvroContaineOutputFormat' for creating table in Hive from Hbase.

Re: HBase table map to hive
Hi! You can use map<String,something> on your column family or a prefix of column qualifier. https://cwiki.apache.org/confluence/display/Hive/HBaseIntegration#HBaseIntegration-HiveMAPtoHBaseColumnFamily -- Kind regards/ Pozdrawiam, Wojciech Indyk http://datacentric.pl 2016-04-04 14:13 GMT+02:00 ram kumar <ramkumarro...@gmail.com>: > Hi, > > I have a hbase table with column name changes (increases) over time. > Is there a way to map such hbase to hive table, > inferring schema from the hbase table? > > Thanks
HBase table map to hive
Hi, I have a hbase table with column name changes (increases) over time. Is there a way to map such hbase to hive table, inferring schema from the hbase table? Thanks
Re: HBase table map to hive
yes you can Register table in hive based in hbase CREATE EXTERNAL TABLE IF NOT EXISTS DB_NAME.TABLE_NAME(COL1 STRING,COL2 STRING,COL3 STRING) STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler' WITH SERDEPROPERTIES ("hbase.columns.mapping" = ":key,cf:COL2,cf:COL3") TBLPROPERTIES ("hbase.table.name" = "HBASE_TABLE_NAME", "hbase.mapred.output.outputtable" = "HBASE_TABLE_NAME"); On 11 March 2016 at 16:49, ram kumar <ramkumarro...@gmail.com> wrote: > Hi, > I have a HBase table with rowkey and column family. > Is it possible to map HBase table to hive table? > > Thanks >
HBase table map to hive
Hi, I have a HBase table with rowkey and column family. Is it possible to map HBase table to hive table? Thanks
