Re: How to Use Nifi Remote Debugger?

2016-09-22 Thread Oleg Zhurakousky
Also, keep in mind that while remote debugging helps with something that may 
already be running in production, for pure development there is a simpler way 
to run NiFi in debug mode without using remote debugger.
Here is more information -

It appears that it was an issue with the port 8000, when I moved it to
something random then Nifi would start up.

I¹m connecting to an EC2 that I¹ve set up because I need to test some
AWS
communication. Now that I have Nifi running, I¹m trying to connect with
the debugger and getting the following error:

Error running AWS Nifi: Unable to open debugger port
(xx.xxx.xxx.xxx:5500): java.net.ConnectionException ³Operation timed
out²

Does this seem like a networking error? Pretty sure my security groups
have opened up all port communication if coming from my IP.

Has remote debugging changed in the past year or so since that thread

Re: ExecuteProcessor Not Removing Flowfile from Queue

Hey Breandán,

session.create() will create a brand new FlowFile, not retrieve one from

ExecuteProcessor Not Removing Flowfile from Queue

2016-09-22 Thread Breandan Mac Parland
Hi,

I have a simple workflow whereby a flowfile is passed into an ExecuteScript 
processor. This runs the following python in the Script Body:

ff = session.create()
session.transfer(ff, REL_SUCCESS)

This transfers the flowfile to the success path, however, the flowfile is never 
removed from the input queue and thus continues to execute again and again. How 
do I remove it from the input queue once the script has run?

p.s. Is there any documentation for this? Best I have found is the 
(unofficial?)

Re: Building a Custom Processor using DBCP Property casting issue

2016-09-22 Thread Bryan Bende
Hello,

Usually this is because the dependencies are not quite right between your
NAR and the NAR where the controller service is.
Your processor project needs a dependency on the API of the controller
service, and your NAR needs a NAR dependency on the NAR where the
controller service implementation is.

The following show examples of how the dependencies work:
https://cwiki.apache.org/confluence/display/NIFI/Maven+Projects+for+Extensions#MavenProjectsforExtensions-LinkingProcessorsandControllerServices
https://github.com/bbende/nifi-dependency-example

The typical way to get a reference to the controller service in your
processor is like this:

final DBCPService dbcpService =
context.getProperty(DBCP_SERVICE).asControllerService(DBCPService.class);

Let us know if it is still not working after verifying the dependencies.

Thanks,

Bryan

Re: How to Use Nifi Remote Debugger?

Hey All,

Thanks so much for the help! The remote debugger ended up working. Because

Building a Custom Processor using DBCP Property casting issue

2016-09-22 Thread Mathias Tiberghien
Hi,

I'm working on version 0.6.1 of Nifi (I'm not allowed to upgrade in this
project) and I have to build a Custom Nifi Processor that read a specific
Excel file and Write the data to Sql.

The process is working fine but I'm facing problem to configure the DBCP
Controller Service Property (as I have to connect to a sql database, I want
to use a connection from a Controller Service).

Looking on PutSQL Processor source code I've devine a ProperptyDescriptor as
below:



public static final PropertyDescriptor ConnectionPool = new
PropertyDescriptor.Builder()
.name("Connection Pool")
.description("JDBC Connection to Database")
.identifiesControllerService(DBCPService.class)
.required(true)
.build();



The Property appears correctly in my Custom Processor on Nifi but when I
drop down the Combobox, the list remains empty. I can create a DBCP
Controller Service trough the Combobox and it appears in the list of my
services, but not in the combobox (I only see the service id)



Did I missed something in the dependencies of my project (see Pom.xml
attached)



I also tried this:

String connection = "ExistingDBCPControllerServiceName";
ControllerServiceLookup lookup = context.getControllerServiceLookup();
Set identifiers =
lookup.getControllerServiceIdentifiers(ControllerService.class);
if(identifiers.size()==0)log.error("No identifiers found for
ControllerService");
Iterator it = identifiers.iterator();
ControllerService service = null;
boolean found = false;
while(it.hasNext())
{

String id = it.next();
String name = lookup.getControllerServiceName(id);
   service = lookup.getControllerService(id);
log.warn(String.format("Service id: %s, name: %s, class:
%s",id,name,service.getClass()));
if(name.equals(connection))
{
found=true;
}
if(found)break;
}



Usting the ControllerServiceLookup and get a known ControllerService.

When I display the service class, it does not appear as DBCPService but as a
com.sun.Proxy$Proxy89 class and I cannot cast the service to a DBCPService



If I use the code below:

try
{
m = service.getClass().getMethod("getConnection",null);
Connection conn = (Connection) m.invoke(service,null);
//Cod
}
catch (NoSuchMethodException ex)
{
log.error("Method getConnection not found: "+ex.getMessage());
}



I can retrieve the Connection from the Proxy



I'm not familiar coding in java (I'm a C# developer) but it seems that some
dependency is missing and that my processor can't parse processor proxy
correctly



I'd be very grateful if you have any clue on this.

Re: [E] LIST_SFTP FETCH_SFTP

2016-09-22 Thread HadyZiade

workaround to store the processed file in memory and have a process do a
lookup with that file to pull unprocessed files only ...
