csv2parquet's Issues

Error related to com.google.common.base.Stopwatch

Hello,

Thanks for this script.

I installed Apache Drill 1.10.0 on my (AWS) Linux server, and installed Python 3.6

When I run the script, after several seconds, the CLI returns without any error.

And I get an output file as specified in the params.

However, my output file is empty (the input file is 386 mb).

In the Drill logs, I get the error below.

This post (https://issues.apache.org/jira/browse/DRILL-4928) suggests that Netty 4.0.27 or later will cause this issue.

I know very little about Drill or Netty.

Do you have any idea how I can work around this issue?

Thanks!

Option to specify compression?

Hello,

Is there a config option or CLI parameter (or something) that allows me to specify compression options - like SNAPPY, for example?

Thanks!
