Constructor Detail

Abstract

public Abstract(PegasusProperties properties,
                PlannerOptions options)

The overloaded constructor, that is called by the Factory to load the class.

Parameters:

properties - the properties object.

options - the options passed to the Planner.

Method Detail

applyPriority

public void applyPriority(TransferJob job)

Applies priorities to the transfer jobs if a priority is specified in the properties file.

Specified by:

applyPriority in interface Implementation

Parameters:

job - the transfer job .

checkAndTransferProxy

public boolean checkAndTransferProxy(TransferJob job)

Determines if there is a need to transfer proxy for the transfer job or not. If there is a need to transfer proxy, then the job is modified to create the correct condor commands to transfer the proxy. Proxy is usually transferred if the VDS profile TRANSFER_PROXY is set, or the job is being run in the condor vanilla universe. The proxy is transferred from the submit host (i.e site local). The location is determined from the value of the X509_USER_PROXY profile key associated in the env namespace.

Specified by:

checkAndTransferProxy in interface Implementation

Parameters:

job - the transfer job .

Returns:

boolean true job was modified to transfer the proxy, else false when job is not modified.

setRefiner

public void setRefiner(Refiner refiner)

Sets the callback to the refiner, that has loaded this implementation.

Specified by:

setRefiner in interface Implementation

Parameters:

refiner - the transfer refiner that loaded the implementation.

addSetXBitJobs

protected boolean addSetXBitJobs(SubInfo computeJob,
                                 SubInfo txJob,
                                 Collection execFiles)

Adds the dirmanager to the workflow, that do a chmod on the files being staged.

Parameters:

computeJob - the computeJob for which the files are being staged.

txJob - the transfer job that is staging the files.

execFiles - the executable files that are being staged.

Returns:

boolean indicating whether any XBitJobs were succesfully added or not.

addSetXBitJobs

public boolean addSetXBitJobs(String computeJobName,
                              String txJobName,
                              Collection execFiles,
                              int transferClass)

Adds the dirmanager job to the workflow, that do a chmod on the files being staged.

Specified by:

addSetXBitJobs in interface Implementation

Parameters:

computeJobName - the name pf the computeJob for which the files are being staged.

txJobName - the name of the transfer job that is staging the files.

execFiles - the executable files that are being staged.

transferClass - the class of transfer job

Returns:

boolean indicating whether any XBitJobs were succesfully added or not.

getSetXBitJobName

public String getSetXBitJobName(String name,
                                int counter)

Generates the name of the setXBitJob , that is unique for the given workflow.

Specified by:

getSetXBitJobName in interface Implementation

Parameters:

name - the name of the compute job

counter - the index for the setXBit job.

Returns:

the name of the setXBitJob .

createSetXBitJob

protected SubInfo createSetXBitJob(FileTransfer file,
                                   String name)

Creates a dirmanager job, that does a chmod on the file being staged. The file being staged should be of type executable. Though no explicit check is made for that. The staged file is the one whose X bit would be set on execution of this job. The site at which job is executed, is determined from the site associated with the destination URL.

Parameters:

file - the FileTransfer containing the file that has to be X Bit Set.

name - the name that has to be assigned to the job.

Returns:

the chmod job, else null if it is not able to be created for some reason.

getPriority

protected String getPriority(TransferJob job)

Returns the priority for the transfer job as specified in the properties file.

Parameters:

job - the Transfer job.

Returns:

the priority of the job as determined from properties, can be null if invalid value passed or property not set.

getPathToUserProxy

protected String getPathToUserProxy()

Returns the path to the user proxy from the pool configuration file and the properties file. The value in the properties file overrides the value from the pool configuration file.

Returns:

path to user proxy on local pool. null if no path is found.
