Parquet Nodes in Arm64 based Mac’s environment

[ksimecek]

Hello,

I describe my problem with Parquet nodes (Read/Write) in KNIME on Arm64 Mac environment.

In KNIME 4.6.4 or 4.7.X on Intel (with Rosetta) I have installed Big Data extensions:

• KNIME Column Storage (based on Apache Parquet)
• KNIME Extension for Big Data File Formats

And result is I have in KNIME 4.6.4 or 4.7.X on Intel (with Rosetta) Parquet nodes, see picture.

In KNIME 4.7.X on Arm64 I have installed Big Data extensions too, see picture:

• KNIME Column Storage (based on Apache Parquet)
• KNIME Extension for Big Data File Formats

But result is I have not Parquet nodes in KNIME 4.7.X on Arm64 see picture.

and I have errors in log, see picture.

My opinion is, that between KNIME 4.7.X on Arm64 environment and another KNIME environments is “some little different”, what installation of extensions do not detect as problem or do not change configuration of extensions for Arm64 environment correct.

@ksimecek there is currently a bug with the version 4.7 and Apple Silicon that makes ist unusable unfortunately - tickets for that are open (AP-19894, AP-19918). Version 5.0 seems to have similar problems for the M1 and M2 chip versions. Solution currently is to use the Intel one - and miss out on the 20%+ speed improvement …

KNIME problem with Extensions on Apple M1

@ksimecek welcome to the KNIME forum. There currently seem to be some problems with the installation of extensions with the M1 / Apple Silicon version. There is already a ticket for that: AP-19894. Until it has been solved my solution is to use the ‚Rosetta‘ version. There the extensions seem to work although the splash screen at the start does not show them.

Hi,

We released a fix with 4.7.2 that should fix the Big Data installation on Arm64 Mac.

@ksimecek can you update and verify if this helps?

Cheers,
Sascha
