QUESTION
I am receiving the error "The query references an object that is not supported in distributed processing mode" when using the HASHBYTES() function to hash rows in Synapse Serverless SQL Pool.
The end goal is to parse the json and store it as parquet along with a hash of the json document. The hash will be used in future imports of new snapshots to identify differentials.
Here is a sample query that produces the error:
...ANSWER
Answered 2021-Jan-06 at 11:19Jason, I'm sorry, hashbytes() is not supported against external tables.
QUESTION
I have a table like this:
...ANSWER
Answered 2021-Apr-14 at 16:00There's no Biml method that can help you detect data type.
I was on a long term project ingesting typeless data from a mainframe and we took a similar approach to what you're doing. We landed data as-is into a table with the widest allowable string type from that system*
We wrote a TSQL script that would unpivot the table and then generate N columns that do analysis on the data. A series of tests would look like (free hand coding so go with the spirit not the letter) :
QUESTION
i would like to deploy Azure landingzone using terraform in multiple subscriptions, Hub network should have azure firewall in subscription1 and each spoke have different subscriptions, i need 4 spokes which would be deployed in 4 separate subscriptions.
can some one help me with logic, how to write terraform.
...ANSWER
Answered 2020-Jun-30 at 06:20For your requirements, here is the architecture that you can follow. The Hub and the spoke are connected via the VNet Peering. According to the description:
The virtual networks can be in the same, or different subscriptions. When you peer virtual networks in different subscriptions, both subscriptions can be associated to the same or different Azure Active Directory tenant.
So you can peer VNets in two different subscriptions. I assume you use the Azure CLI as the authentication your account already login and has enough permission in both two subscriptions. Here is an example code:
QUESTION
I have the data I need in AWS Redshift. It is in a database called Lz (Landingzone). That data inserted into a database called Stage (same redshift). I have the (select) queries that transform the data from it's raw state (LZ) into the dimensions and facts that I need. Traditionally I would use these queries combined with an insert to transform the data. The result would be merged into the datawarehouse (again: same redshift)
How do I do this in Glue? Can I execute the queries in a job using python? Or can i create stored procedures in redshift that are executed by/from jobs?
...ANSWER
Answered 2019-Jun-03 at 07:59I do not think you can run redshift sql in a straighforward and scheduled way from glue at the moment (unfortunately). This is a major omission from the product in my opinion.
There is an option to use pre/post statements as described in this article. this is pretty basic and may not meet your needs.
QUESTION
Using the Azure DevOps REST API and PowerShell, I am trying to create a very basic Release pipeline. My JSON body works fine in Postman, but errors out when run with Invoke-RestMethod in PowerShell.
I'm following the documentation from https://docs.microsoft.com/en-us/rest/api/azure/devops/build/definitions/create?view=azure-devops-rest-5.0.
Using Postman, I've created a JSON body that works perfectly and repeatedly (provided I either change the release pipeline name or delete the previously created one). I've copied the JSON content verbatim to my PowerShell script, setting the variable $requestBody equal to the JSON content. When I run the script, I get an error (see below for error content).
Following is my test script (apologize for the length, but I thought it important I include the entire JSON.
...ANSWER
Answered 2019-Apr-08 at 17:00It looks like you're making a POST to the create build definition API. If you're trying to create a release definition, you probably need to post to a URL like this
QUESTION
I am running HBase on an EMR cluster (emr-5.7.0) enabled on S3. We are using 'ImportTsv' and 'CompleteBulkLoad' utilities for importing the data into HBase. During our process, we have observed that intermittently there were failures stating that there were HFile corruption for some of the imported files. This happens sporadically and there is no pattern that we could deduce for the errors.
After lot of research and going through many suggestions in blogs, I have tried the below fixes but of no avail and we are still facing the discrepancy.
Tech Stack :
AWS EMR Cluster (emr-5.7.0 | r3.8xlarge | 15 nodes)
AWS S3
HBase 1.3.1
Data Volume:
- ~ 960000 lines (To be upserted) | ~ 7GB TSV file
Commands used in sequence:
...
ANSWER
Answered 2018-Feb-12 at 16:25After much research and trial & errors, I was finally able to find a resolution for this issue, thanks to AWS support folks. It seems the issue is an occurrence as a result of S3's eventual consistency. The AWS team suggested to use the below property and it worked like a charm, so far we haven't hit the HFile corruption issue. Hope this helps if someone is facing the same issue!
Property (hbase-site.xml): hbase.bulkload.retries.retryOnIOException : true
QUESTION
I am trying to use the Python Extension to run some code, but when I try to reference columns in the pandas dataframe, it says it cannot find the column:
...ANSWER
Answered 2017-Apr-13 at 21:11It turns out when using anything other than the "VALUES" method of selecting, the column name representation is "b'columnname'". It is basically a stringified representation of the column name as bytes.
QUESTION
I'm trying to copy a file from one folder to another using Files.copy()
and I managed to do that successfully.
But, I want the code to be more flexible by having a message to say "File move unsuccessful!", "File already exists"(if the file is already exists in that folder).
Code:
...ANSWER
Answered 2017-Feb-10 at 13:32The ideal way to deal with errors is to catch exceptions that occur during that process. I am sure you will be able to do that once you study a little harder.
Here is a simple code of try/catch
block you can use it to catch exceptions and see if the operation was successful or not.

Below in the example, I want that each time when the add button is clicked to take the element inside the template div and append it to the landingzone class element. But at the same time I need the NEWID to change for the new element. Of course this is just an example, the table stuff can be a div or anything else.
