Method Detail

convert

public static org.apache.hadoop.hbase.protobuf.generated.ZooKeeperProtos.TableCF[] convert(Map<TableName,? extends Collection<String>> tableCfs)

convert map to TableCFs Object

convertToString

public static String convertToString(Map<TableName,? extends Collection<String>> tableCfs)

convert

public static org.apache.hadoop.hbase.protobuf.generated.ZooKeeperProtos.TableCF[] convert(String tableCFsConfig)

Convert string to TableCFs Object. This is only for read TableCFs information from TableCF node. Input String Format: ns1.table1:cf1,cf2;ns2.table2:cfA,cfB;ns3.table3.

convert

public static String convert(org.apache.hadoop.hbase.protobuf.generated.ZooKeeperProtos.TableCF[] tableCFs)

Convert TableCFs Object to String. Output String Format: ns1.table1:cf1,cf2;ns2.table2:cfA,cfB;table3

getTableCF

public static org.apache.hadoop.hbase.protobuf.generated.ZooKeeperProtos.TableCF getTableCF(org.apache.hadoop.hbase.protobuf.generated.ZooKeeperProtos.TableCF[] tableCFs,
                                                                            String table)

Get TableCF in TableCFs, if not exist, return null.

parseTableCFs

public static org.apache.hadoop.hbase.protobuf.generated.ZooKeeperProtos.TableCF[] parseTableCFs(byte[] bytes)
                                                                                          throws IOException

Parse bytes into TableCFs. It is used for backward compatibility. Old format bytes have no PB_MAGIC Header

Throws:

IOException

parseTableCFsFromConfig

public static Map<TableName,List<String>> parseTableCFsFromConfig(String tableCFsConfig)

Convert tableCFs string into Map.

convert2Map

public static Map<TableName,List<String>> convert2Map(org.apache.hadoop.hbase.protobuf.generated.ZooKeeperProtos.TableCF[] tableCFs)

Convert tableCFs Object to Map.

parsePeerFrom

public static ReplicationPeerConfig parsePeerFrom(byte[] bytes)
                                           throws DeserializationException

Parameters:

bytes - Content of a peer znode.

Returns:

ClusterKey parsed from the passed bytes.

Throws:

DeserializationException

toByteArray

public static byte[] toByteArray(ReplicationPeerConfig peerConfig)

Parameters:

peerConfig -

Returns:

Serialized protobuf of peerConfig with pb magic prefix prepended suitable for use as content of a this.peersZNode; i.e. the content of PEER_ID znode under /hbase/replication/peers/PEER_ID
