Hive to Spark Problem

≫ Next: Feature request: XPath without preview & namespace scan

I installed spark-job-server and configured the enviroment.config to use yarn-client.

When I run hive-to-spark in knime occurs an error described below:

Execute failed: An error occured: java.lang.IllegalArgumentException: Timeout length must not be negative, question not sent to [Actor[akka://JobServer/user/context-supervisor#1663440268]]

I forgot to set up some argument in enviroment.config or cloudera manager?

Dear KNIMErs,

Could we plese get an XPath node without the preview window & namespace scan? It's sure great for small XMLs to see all that, but loading just 90 MB worth of XML routinely freezes my machine, and only thanks to these (apprently memory-inefficient) activities.

Many thanks

Postgres database access

I want to read tables from a postgres database. I configured the driver (I used the build in org.postgresql.driver) and the database in the database reader node. I am able to fetch metadata. But unfortunately the SQL statement gives an error message ".... relation does not excist position ...". Although the table is fetched right I cant read anyting from the table. This table is located in Databases - DAsh_Import-Layer - Schemas -Tables

I found out that it is possible to retrieve information from various systemtables that are located in Databases - Catalogs -PostgreSQL -Tables. This is not the right location for the content. For some reason the Tables are fetched right in the Database reader node but I cant access the right location. Do I configure something wrong, is the database configured wrong or is this a bug?

Thinking this is caused by the driver I tried to install another driver in the preferences - databases screen. I can add the driver.jar. but I don't get a message that it is installed. Even after restarting Knime I cannot select this new driver in te database driver of the node.

Solving this is issue is extremely important for me. I appreciate your help very much.

Hi,

Can you reorder quick form nodes in Knime 3.2 so that they appear in the order you want in the web interface? This was possible with previous version using the Weight field.

Hi all,

I have a scheduled workflow to auto backup a file. The workflow is to get some data from a website and clean it up and save as a csv file. What I need to do in next step is to post it to Box.com and make sure it works well on knime server as well. There is a package in R called boxr that allows me to post the file to box through developer account. However, it requires authentication by logging on through the explorer window. It is not compatible in R snippet in KNIME. Are there any other ways to do? Any solutions??

BTW, i can't find any KREST nodes anymore.

My version of KNIME: 2.12

Thanks :)

Please see the attached image which shows a dendrogram generated from a simple dataset called "teeth" provided by our University. The Hierarchical Clustering node was used in KNIME v3.2.1. The 1st class label is for "HOUSE RAT", the 2nd for "BEAVER", etc, and the 10th is for "HOUSE BAT". Unfortunately this also appears as "HOU...". Are there any options to change the way the text is displayed (and ideally to display the full class label)?

If not, could the node designer consider adding such a feature, please.

Hi Knimers

I still struggling when using R on Knime but I'm getting somewhere :)

My task is run some visualizations from corrplot package (https://cran.r-project.org/web/packages/corrplot/vignettes/corrplot-intr...)

I've done the correlation matrix and its perfect :)

But I can't plot the visualizations :(

Should I use a new R snipet node only to plot

I'm doing this in just one R Snipet:

require(corrplot)
knime.out <- as.matrix(cor(knime.in))
corrplot(knime.out, method="circle")

I always appreciate your help!!!

I encounters an error as detailed in the bottom line knime.log: "This connection has been closed."

DB2 Database connection on MacOS

October 20, 2016, 3:05 am

≪ Previous: the error "This connection has been closed." will occured using PostgreSQL Connector

Hi,

I'm new to the Knime community and am trying to set up a connection to a DB2 database using my Mac. Since the db2 driver is not in the native display, i had to add it via preferences and followed all the steps by adding the driver files. From the preferences side i have the option of picking (DB2 for : i5/OS; Linux, Unix, windows or z/OS) and a version: are these driver configurations system version specific?. I added all the parameters but I'm having issues adding the drivers and having it listed as a dropdown option on the connection side. Not sure if this is a driver issue or a Mac issue.

I've gone through the connection process using a windows machine and everything works fine (adding drivers, seeing driver, selecting the driver, seeing metadata etc.) Anybody know what may be happening or can point be to an answer somewhere on here.

Thanks

Problem with POST request to Google Sheets

Hi,

We are new to KNIME and we are struggling to connect it to Google sheets.

We want to post the output dataset of our workflow into a Gsheet,for which we are using the REST services POST request node. After reading all the docummentation about this node, we are still unable to do this! We can do post requests to gsheets through our own applications but these same settings don't seem to work on the node.

Has anyone succesfully posted something onto gsheets? If so, could we see an example on how to fill in the node or do you have any documentation on this specific topic?

Many thanks!
