Not Windows-compatible due to mkfifo call in NetezzaUtils #7

Open abradbury opened 8 years ago

abradbury commented 8 years ago

Hello, I am using Spark 1.5.0 in Scala with spark-netezza 0.1.1 on a Windows 7 machine.

Running Spark with the spark-netezza connector configured as detailed in the README results in the following error and stack trace (the full stack trace is included at the end):

This seems to be because of line 51 of NetezzaUtils.scala, which calls the mkfifocommand, which is a Linux-only command and, hence, would fail on Windows. Perhaps this StackOverflow question and answers would help with information about making such a step of the connector platform agnostic?

Thank you.

Thank you for reporting this issue. Did u you try using cygwin ? I currently don't have Windows setup to try the fix you suggested above.
