Method Detail

assigned

public static void assigned(KeyExtent extent,
                            TServerInstance server)

A decision was made to assign a tablet to a tablet server process. Accumulo will stick to this decision until the tablet server loads the tablet or dies.

loading

public static void loading(KeyExtent extent,
                           TServerInstance server)

A tablet server has received an assignment message from manager and queued the tablet for loading.

suspended

public static void suspended(KeyExtent extent,
                             HostAndPort server,
                             long time,
                             TimeUnit timeUnit,
                             int numWalogs)

unsuspended

public static void unsuspended(KeyExtent extent)

loaded

public static void loaded(KeyExtent extent,
                          TServerInstance server)

unassigned

public static void unassigned(KeyExtent extent,
                              int logCount)

split

public static void split(KeyExtent parent,
                         KeyExtent lowChild,
                         KeyExtent highChild,
                         TServerInstance server)

missassigned

public static void missassigned(KeyExtent extent,
                                String goalState,
                                String currentState,
                                TServerInstance future,
                                TServerInstance current,
                                int walogs)

Called when a tablet's current assignment state does not match the goal state.

selected
