zengchuan commented on HIVE-1245:
---------------------------------
I'm new to hbase and hive. I create a table in hbase and add data array into it.
public static void createTable(String tablename) throws IOException{
HBaseAdmin admin = new HBaseAdmin(hbaseConfig);
if(admin.tableExists(tablename)){
System.out.println("table Exists!!!");
}else{
HTableDescriptor tableDesc = new HTableDescriptor(tablename);
tableDesc.addFamily(new HColumnDescriptor("dom"));
admin.createTable(tableDesc);
}
}
public static void addData(String tablename) throws IOException{
HTable table=new HTable(hbaseConfig,tablename);
Put put = new Put(Bytes.toBytes(String.valueOf(i)));
List<String> a = new ArrayList<String>();
a.add("domain1");
a.add("domain2");
Object obj = doType(hbaseConfig, a, List.class);
Writable w = new HbaseObjectWritable(obj);
byte[] depthMapByteArray = WritableUtils.toByteArray(w);
put.add(Bytes.toBytes("dom"),
Bytes.toBytes("domain"),
depthMapByteArray
);
table.put(put);
}
private static Object doType(Configuration conf, Object value,
Class<?> clazz)
throws IOException {
ByteArrayOutputStream byteStream = new ByteArrayOutputStream();
DataOutputStream out = new DataOutputStream(byteStream);
HbaseObjectWritable.writeObject(out, value, clazz, conf);
out.close();
ByteArrayInputStream bais =
new ByteArrayInputStream(byteStream.toByteArray());
DataInputStream dis = new DataInputStream(bais);
Object product = HbaseObjectWritable.readObject(dis, conf);
dis.close();
return product;
}
in hive i create a table
CREATE EXTERNAL TABLE hbase_table_2(row_key int, domain Array<String>)
STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'
WITH SERDEPROPERTIES ("hbase.columns.mapping" = ":key,dom:domain")
TBLPROPERTIES("hbase.table.name" = "table2");
in hbase_table_2 domain Array<String> is not right. why?
> allow access to values stored as non-strings in HBase
