Subject Re: Schema read issue
Date Wed, 16 May 2018 16:26:17 GMT
Hey Fawze,

This is expected to work seamlessly (although that's a pretty big
upgrade). Do the logs report any issues? Does comparing the schemas of
the before/after upgrade-written files using 'parquet-tools schema
<file>' show any differences?

Thanks!
