Method Detail

setCompression

public void setCompression(org.apache.hadoop.hbase.HColumnDescriptor cd,
                           String algorithm)

Description copied from interface: HBaseCompat

Configure the compression scheme algorithm on a column family descriptor cd. The algorithm parameter is a string value corresponding to one of the values of HBase's Compression enum. The Compression enum has moved between packages as HBase has evolved, which is why this method has a String argument in the signature instead of the enum itself.

Specified by:

setCompression in interface HBaseCompat

Parameters:

cd - column family to configure

algorithm - compression type to use

newTableDescriptor

public org.apache.hadoop.hbase.HTableDescriptor newTableDescriptor(String tableName)

Description copied from interface: HBaseCompat

Create and return a HTableDescriptor instance with the given name. The constructors on this method have remained stable over HBase development so far, but the old HTableDescriptor(String) constructor & byte[] friends are now marked deprecated and may eventually be removed in favor of the HTableDescriptor(TableName) constructor. That constructor (and the TableName type) only exists in newer HBase versions. Hence this method.

Specified by:

newTableDescriptor in interface HBaseCompat

Parameters:

tableName - HBase table name

Returns:

a new table descriptor instance

createConnection

public ConnectionMask createConnection(org.apache.hadoop.conf.Configuration conf)
                                throws IOException

Specified by:

createConnection in interface HBaseCompat

Throws:

IOException

addColumnFamilyToTableDescriptor

public void addColumnFamilyToTableDescriptor(org.apache.hadoop.hbase.HTableDescriptor tableDescriptor,
                                             org.apache.hadoop.hbase.HColumnDescriptor columnDescriptor)

Specified by:

addColumnFamilyToTableDescriptor in interface HBaseCompat

setTimestamp

public void setTimestamp(org.apache.hadoop.hbase.client.Delete d,
                         long timestamp)

Specified by:
