Constructor Detail

RmQueriedMachine

public RmQueriedMachine(String name,
                        String nodepoolId,
                        long memory,
                        int order,
                        boolean blacklisted)

Method Detail

setOffline

public void setOffline()

setUnresponsive

public void setUnresponsive()

addShare

public void addShare(RmQueriedShare rqs)

getShares

public List<RmQueriedShare> getShares()

Return the list of shares scheduled to this host.

Returns:

The list of shares.

getId

public String getId()

Returns the name of the machin.

Returns:

the name of the machine.

getMemory

public long getMemory()

Returns the amount of RAM in KB (kilobytes) on the machine.

Returns:

the amount of RAM in the machine, in kilobytes.

getShareOrder

public int getShareOrder()

Returns the share order of the machine.

Returns:

the number of quantum shares supported by the machine. For example, if the share quantum is 15GB, a 48GB machine is of order 3.

isBlacklisted

public boolean isBlacklisted()

Returns whether the machine is blacklisted.

Returns:

whether the host contains blacklisted processes. A blacklisted process is one whose characteristics no longer match the machine. For example, after reconfiguration, this may be an illegal assignemnt for the request. Until such time as the request is (externally) removed, the RM has to account for the space by maintaining records on the blacklisted work. If a machine is blacklisted, it is not schedulable for new work.

isOnline

public boolean isOnline()

Returns whether the machine is varied online.

Returns:

true if the machine is varied online and false otherwise. Note that a machine might "not varied offline", but not responsive (not sending heartbeats).

isResponsive

public boolean isResponsive()

Indicates whether the machine is sending heartbeats.

Returns:

true if the machine is sending heartbeats. Note that a machine might be sending heartbeats but be varied offline or blacklisted, and hence not schedulable.

toString

public String toString()

Overrides:

toString in class Object
