Currently I have a dataflow with the GetFile processor that taps into a directory path with TSV files. I want to convert these TSV files to CSV for later work using the ConvertCSVToAvro processor. I've created this python script with a .bash wrapper to test it: import sys
import csv
tsvin = csv.reader(sys.stdin, dialect=csv.excel_tab)
commaout = csv.writer(sys.stdout, dialect=csv.excel)
for row in tsvin:
commaout.writerow(row)
bash wrapper for file in *.tsv
do
python tsv2csv.py < $file > ${file%.*}.csv
done
I see the ExecuteScript processor as a possible option. How would I use it to execute this python script--would the processor know where to import from for example...or is there a better way to convert?

To those techie pioneers that may be following behind me: I decided to follow the trail of the missing address assignments inherent in the "device eth0 does not seem to be present" from the guest opsys. I looked on my laptop's network devices to confirm that the network adapter that I needed (VMNet8) was missing in action. Here are the steps I followed.

While I've been able to get a 2.4 vmware player sandbox to work on my desktop under a NAT adapter without issue, I cannot get a second vmware player to work in a wireless environment on a laptop. The choices I've made so far for the network settings on the guest vm have been NAT or NAT Networking. Both of these choices return the same results-- an error on startup which reads: device eth0 does not seem to be present, then: Connectivity Issues Detected! when the startup process has completed. No IP address is displayed. Well, the vm isn't wrong since I don't have any ports/addresses set up--but I haven't a clue how to bridge the dynamic wireless environment to ip addresses/ports. I am not a network geek, so this has turned out to be a frustrating stumbling block. Please advise.

For others behind me: I found this advice on clearing off the canvas here. From what I can tell, you can not select a previous template from the template management window. There is another template icon next to the funnel icon. Drag it over to the canvas. You'll see a drop down which lists the templates. The one you select will be instantiated.

Techies, Can someone please tell me how to do the following 2 things: 1. Clear the flow diagramming canvas of all previous dataflows. 2. Load an existing template onto the diagramming canvas workspace.

Karthik, That is a good idea. I can manually install Maven! Thank you so much for answering my question.

Thanks Karthik--I am not directly using either. The curl statement is embedded somewhere. Do you know where, or how I can bypass the failure event?

Fellow Techies-- The VNC install on Ambari failed on: resource_management.core.exceptions.Fail: Execution of 'curl -o /etc/yum.repos.d/epel-apache-maven.repo https://repos.fedorapeople.org/repos/dchen/apache-maven/epel-apache-maven.repo' returned 35. curl: (35) SSL connect error When I issue the statement interactively to avoid the SSL error through my ssh terminal as: curl -o /etc/yum.repos.d/epel-apache-maven.repo http://repos.fedorapeople.org/repos/dchen/apache-maven/epel-apache-maven.repo , the file downloads as expected.
Where or how do I edit this? Here's what I see on the config page for the VNC Server install. The curl statement must be embedded in one of the *.tar files. Please advise on what the next step is toward resolution.

For those newbies following this thread: The file was absent of any data because the default vnc-env-template did not have at least the vnc_user and vnc_geometry set. While this may not be what you want, at least the default entry will there to work with.
