Hello there, i have compiled the HBase source code and i;m running
locally the HMaster. However when i try to create a table and insert
rows with an HBaseClient there are some problems. I would appreciate
your help , thanks in advance.
HBaseClient :
Configuration config = new HBaseConfiguration().create();
HBaseAdmin admin = new HBaseAdmin(config);
System.out.println("Is Master running?? " + admin.isMasterRunning());
try{
admin.createTable(new HTableDescriptor("myLittleHBaseTable"));
}catch(org.apache.hadoop.hbase.TableExistsException e){
System.out.println("Propably the requested table already exists!!");
}
try{
admin.addColumn("myLittleHBaseTable", new
HColumnDescriptor(Bytes.toBytes("myLittleFamily")));
}catch(org.apache.hadoop.hbase.InvalidFamilyOperationException e){
System.out.println("Propably there is some fault with column!!");
}
HTableDescriptor tables [] ;
tables = admin.listTables();
System.out.println("Existing tables : ");
for(int i =0; i<tables.length;i++){
System.out.println(tables[i].toString());
}
HTable table = new HTable(config,"myLittleHBaseTable");
Put p = new Put(Bytes.toBytes("myLittleRow"));
p.add(Bytes.toBytes("myLittleFamily"),
Bytes.toBytes("myLittleQualifier"),Bytes.toBytes("Some Value"));
table.put(p);
The output is below :
