I want to open a parquet file and view the contents of the table in Intellij. Is there a way to do this currently or with a plugin?
You need to install: Avro and Parquet Viewer plugin in order to view this kind of file:
https://plugins.jetbrains.com/plugin/12281-avro-and-parquet-viewer
If you just want to open a Parquet file, it is part of the Big Data Tools plugin (JetBrain's official). Just install it and then double click the file it will open in the editor as a table.
The answer for you is no, at least now.
But if the reason you want to view Parquet tables on Intellij is because you want to view Parquet file with GUI tool, I suggest you use tools Bigdata File Viewer.
It's a desktop application to view Parquet and also other binary format data like ORC and AVRO. It's pure Java application so that can be run at Linux, Mac and also Windows.
It supports complex data type like array, map, etc.

I have some Apache Parquet file. I know I can execute parquet file.parquet in my shell and view it in terminal. But I would like some GUI tool to view Parquet files in more user-friendly format. Does such kind of program exist?
Check out this utility. Works for all windows versions: https://github.com/mukunku/ParquetViewer
There is Tad utility, which is cross-platform. Allows you to open Parquet files and also pivot them and export to CSV. Uses DuckDB as it's backend. More info on the DuckDB page:

Actually I found some Windows 10 specific solution. However, I'm working on Linux Mint 18 so I would like to some Linux (or ideally cross-platform) GUI tool. Is there some other GUI tool?

There is a GUI tool to view Parquet and also other binary format data like ORC and AVRO. It's pure Java application so that can be run at Linux, Mac and also Windows. Please check Bigdata File Viewer for details.
It supports complex data type like array, map, struct etc. And you can save the read file in CSV format.
GUI option for Windows, Linux, MAC
You can now use DBeaver to
view parquet data
view metadata and statistics
run sql query on one or multiple files. (supports glob expressions)
generate new parquet files.
DBeaver leverages DuckDB driver to perform operations on parquet file. Features like Projection and predicate pushdown are also supported by DuckDB.
Simply create an in-memory instance of DuckDB using Dbeaver and run the queries like mentioned in this document. Right now Parquet and CSV is supported.
Here is a Youtube video that explains the same - https://youtu.be/j9_YmAKSHoA
JetBrains (IntelliJ, PyCharm etc) has a plugin for this, if you have a professional version: https://plugins.jetbrains.com/plugin/12494-big-data-tools
I have .sql file, I want to convert it to NoSQL, as I have a coursework on MongoDB.
What application can I use or how can I do it?
In a quick Google search, I found this website that converts CREATE and INSERT INTO statements to a JSON or Javascript format. However, if you want to create a different database structure (which I would probably recommend), you might want to program a Python script to create a JSON file to import to MongoDB. I guess it all depends on what you want to create.
We have a custom internal data format. I'd like to use Impala with this format, just for reading. I want to write the binding for this format. But there is no reason to contribute this back, as nobody else uses this format.
Does Impala support file format plugins in some way?
From hdfs-scan-node.cc it looks like the list of file formats is hardcoded unfortunately. If this is the case, is there a plan to change this? Or is this not a common problem for some reason?
No, as stated in How Impala Works with Hadoop File Formats:
Impala can only query the file formats listed in the preceding table. In particular, Impala does not support the ORC file format.
The reasons for this are probably related to the run-time code generation which would be harder to optimize if Impala didn't constrain file formats.
However, Impala is an open source project and there is no reason why you cannot suggest this by filing a JIRA.

I am attempting to use Automator to turn a folder of ArtPro (.ap) images into .pdf's, but I can't find any existing or downloadable actions to do anything other than open a .ap file with automator.
Does anyone know of an action I could download or a different way to automate the conversion of .ap to .pdf? Is it possible to do it using applescript instead?
It is only possible with ArtPro itself (manually) or Automation Engine's Action List. You can try recording your actions with "Watch-me-do" in Automator, but it's not a good idea. Apple Script will not help.
The problem is that Esko has its own file format which no other software can understand.
I could see some approaches:
a) open the document in ArtPro, then use the Print command and write out as PDF
b) (if Preview.app can read in .ap files) open the document in Preview.app and save as PDF
c) if there is no direct way (a) or b)), write out as TIFF and convert that intermediate file, for example in Acrobat or Preview
The ArtPro format is proprietary to Esko - you won't be able to open it in anything else.
Secondly, Esko favours selling its own automation solution (Automation Engine) - ArtPro will not allow you to automate it. It doesn't integrate with Automator and as far as I know it also doesn't publish AppleScript actions.
So basically I think your only option is using Automation Engine from Esko.
You need used task "Export ArtPro to Normalized PDF File" in esko automation engine
I am facing problem while generating CAB file. I want to customize the INF file generation depending upon what components I choose to package. At present, we need to modify the INF file manually to include/exclude the components. I would just like to know, is there any programmatic interface where I will give the paths of the components to be packaged and it will give me INF file. This file I will provide to cabwiz.exe to generate the CAB archive. I am searching this type of solution because I want to avoid VS installation on non-developer's machine.
Thanks,
Omky
I'm not aware of any "programmatic interface for INF generation", but that said, it would be pretty trivial to create one. The INF format is pretty straightforward with not a lot of sections or options, and many of which you can safely ignore.
I created a tool some time back that generated an INF that would parse a desktop file/directory tree and generate an INFo that would replicate the same tree on the device with the same files. Basically you'd build the tree on the PC that you wanted on the device and the tool would read what you had, build an INF and then package it (I'd actually post the code, but I can't find it offhand). It took maybe an hour to write.
