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? ... View more

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. ... View more

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. ... View more

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. ... View more

Hi Fellow Techies-- I'm pretty close to standing up VNC--however the install failed with the only clue in Ambari that I could find. The file /etc/sysconfig/vncservers and the file /etc/sysconfig/vncservers.bak exist (read: re-install after the first failure). What should these empty files contain--or is this a "red herring" message? 2016-12-07 01:35:59,048 - Execute['mv /etc/sysconfig/vncservers /etc/sysconfig/vncservers.bak >> /var/log/vnc-stack.log'] {'ignore_failures': True} 2016-12-07 01:35:59,391 - File['/etc/sysconfig/vncservers'] {'owner': 'root', 'content': InlineTemplate(...), 'group': 'root', 'mode': 0644} 2016-12-07 01:35:59,397 - Writing File['/etc/sysconfig/vncservers'] because it doesn't exist ...
