Spring xd stream - kafka

[bigdata hadoop <ha...@gmail.com>]

Hi Kafka Users
I am new to streams in spring xd and trying to consumer data from a topic.
I downloaded the spring xd single node on my laptop and ran the following
command:

1. stream create myKafka --definition "kafka
--zkconnect=localhost:2181 --topic=mytopic | log" --deploy

I did not see the log where it deployed. I checked under/tmp and
/xd/logs I did not find any. Where do I need to look for log.

Saw in C:\tmp\kafka-logs\myKafka-kafka-offsets-0 but was not sure how
to read this log. I did more and filename but it was unreadable file.

2. stream create myKafkaFile --definition "kafka
--zkconnect=localhost:2181 --topic=mytopic | file" --deploy

Tried this statement then got the numbers format of file under /tmp/xd/output.

Tried adding

stream create myKafkaFile --definition "kafka
--zkconnect=localhost:2181 --topic=mytopic | file
--outputType=text/plain" --deploy

and

stream create myKafkaFile --definition "kafka
--zkconnect=localhost:2181 --topic=msi_client_topic | file --mode=ref
--dir=/tmp/xd/output --pattern=*.txt" --deploy

and --binary=false

but was throwing error and did not deploy my stream.

I have JSON String in topic, Can any one please help with this to read
as a JSON string instead of numbers.

Thanks
