getTableId

public static TableId getTableId(ClientContext context,
                                 String tableName)
                          throws TableNotFoundException

Lookup table ID in ZK. Throw TableNotFoundException if not found. Also wraps NamespaceNotFoundException in TableNotFoundException if namespace is not found.

Throws:

TableNotFoundException

_getTableId

public static TableId _getTableId(ClientContext context,
                                  String tableName)

                                  TableNotFoundException

Lookup table ID in ZK. If not found, clears cache and tries again.

Throws:

NamespaceNotFoundException

TableNotFoundException

getTableName

public static String getTableName(ClientContext context,
                                  TableId tableId)
                           throws TableNotFoundException

Throws:

TableNotFoundException

getTableOfflineMsg

public static String getTableOfflineMsg(ClientContext context,
                                        TableId tableId)

getNameToIdMap

public static Map<String,TableId> getNameToIdMap(ClientContext context)

getIdToNameMap

public static Map<TableId,String> getIdToNameMap(ClientContext context)

exists

public static boolean exists(ClientContext context,
                             TableId tableId)

clearCache

public static void clearCache(ClientContext context)

clearCacheByPath

public static void clearCacheByPath(ClientContext context,
                                    String zooPath)

Clears the zoo cache from instance/root/{PATH}

Parameters:

context - The Accumulo client context

zooPath - A zookeeper path

getPrintableTableInfoFromId

public static String getPrintableTableInfoFromId(ClientContext context,
                                                 TableId tableId)

getPrintableTableInfoFromName

public static String getPrintableTableInfoFromName(ClientContext context,
                                                   String tableName)

getTableState

public static TableState getTableState(ClientContext context,
                                       TableId tableId)

getTableState

public static TableState getTableState(ClientContext context,
                                       TableId tableId,
                                       boolean clearCachedState)

Get the current state of the table using the tableid. The boolean clearCache, if true will clear the table state in zookeeper before fetching the state. Added with ACCUMULO-4574.

Parameters:

context - the Accumulo client context

tableId - the table id

clearCachedState - if true clear the table state in zookeeper before checking status

Returns:

the table state.
