Re: Problems with Flume on windows with HTTP source

Hi Hari and the all members of this list,

Thanks for pointing me that error. This is actually my second attempt to
use Apache Flume - with avro client. The symptoms are the same - the is no
listener on the specified port and I am not able to connect.

I started to evaluate Flume just yesterday and many things are new to me
and probably I do many mistakes. I want to point that I use Flume 1.3.1
compiled by me if this is important to be mentioned. I have tested too with
the official binary from Flume web site but the results are the same.

Here is what I do to test HTTP source:

my config file (httppost.conf):
agent1.sources = r1
agent1.channels = ch1
agent1.sinks = k1

agent1.sources.r1.type = org.apache.flume.source.http.HTTPSource
agent1.sources.r1.port = 9001
agent1.sources.r1.channels = ch1
#agent1.sources.r1.handler = org.example.rest.RestHandler
agent1.sources.r1.handler = org.apache.flume.http.JSONHandler
agent1.sources.r1.handler.nickname = json handler

agent1.sinks.k1.type = file_roll
agent1.sinks.k1.channel = ch1
agent1.sinks.k1.sink.directory C:\\Projects\\nickyk\\apache-flume-1.3.1-bin\\log

agent1.channels.ch1.type = memory
agent1.channels.ch1.capacity = 10000
agent1.channels.ch1.transactionCapacity = 1000

my server bat file:
set FLUME_HOME=C:\Projects\nickyk\apache-flume-1.3.1-bin\
set JAVA="C:\Java\jdk1.6.0_45\bin\java.exe"
set JAVA_OPTS=-Xmx60m
set CONF=%FLUME_HOME%\conf\httppost.conf
set AGENT=agent1

%JAVA% %JAVA_OPTS%
-Dlog4j.configuration=file:///%FLUME_HOME%\conf\log4j.properties -cp
"%FLUME_HOME%\lib\*" org.apache.flume.node.Application -f %CONF% -n %AGENT%

How I test:

server console:
>"C:\Java\jdk1.6.0_45\bin\java.exe" -Xmx60m
-Dlog4j.configuration=file:///C:\Projects\nickyk\apache-flume-1.3.1-bin\\conf\log4j.properties
-cp "C:\Projects\nickyk\apache-flume-1.3.1-bin\\lib\*"
org.apache.flume.node.Application -f
C:\Projects\nickyk\apache-flume-1.3.1-bin\\conf\httppost.conf -n agent1

client console:
>C:\Projects\nickyk\apache-flume-1.3.1-bin>curl -X POST -H "Content-Type:
application/json" -d "[{ \"headers\" : { \"timestamp\" : \"434324343\",
\"host\" : \"random_host.example.co
m\" }, \"body\" : \"random_body\" }, { \"headers\" : { \"namenode\" : \"
namenode.example.com\", \"datanode\" : \"random_datanode.example.com\" },
\"body\" : \"really_random_body\"
}]" http://localhost:9001
curl: (7) Failed connect to localhost:9001; No error

If I understand correct the documentation I should expect that on the
specified port (9001) it must be listener that will accept POST requests?
Is this correct?
Do I miss some important aspects that are critical to run Flume?

Thanks in advance for your help.
best regards,
nickolay kolev
