Known issues with usability.
- An application can become stuck with the status 'starting' and the user might not be
able to find the 'restart' or 'delete' action button.This could be caused by a failure
in the selected application script.The exact errors can be found in the logs of the
application in the individual description page.
Workaround: Stop the application from the UI and then Restart the application once the issue in the script is addressed.
- The Options tab on the Project Settings page is now only viewable to the Administrator. This is because the Private and Team visibility options on the Options page are only viewable by the Administrator.
Environment variables with the dollar ($) character are not parsed correctly by CDSW. For example, if you set
PASSWORD="pass$123"in the project environment variables, and then try to read it using the echo command, you see the following output:
pass23Workaround: Use one of the following commands to print the $ sign:
echo 24 | xxd -r -p or echo JAo= | base64 -dInsert the value of the environment variable by wrapping it in the command substitution using $() or ``. For example, if you want to set the environment variable to
ABC$(echo 24 | xxd -r -p)123 or ABC`echo 24 | xxd -r -p`123
In some cases, the application switcher (grid icon) does not show any other applications, such as Hue or Ranger.
Cloudera Bug: DSE-865
Scala sessions hang when running large scripts (longer than 100 lines) in the Workbench editor.
Execute the script in manually-selected chunks. For example, highlight the first 50 lines and select.
Restructure your code by moving content into imported functions so as to bring the size down to under 100 lines.
The R engine is unable to display multi-byte characters in plots. Examples of multi-byte characters include languages such as Korean, Japanese, and Chinese.Workaround: Use the
showtextR package to support more fonts and characters. For example, to display Korean characters:
install.packages('showtext') library(showtext) font_add_google("Noto Sans KR", "noto") showtext_auto()

In a scenario where 100s of users are logged in and creating processes, the
nofilelimits of the system may be reached. Use
ulimitsor other methods to increase the maximum number of processes and open files that can be created by a user on the system.
When rebooting, Cloudera Data Science Workbench hosts can take a significant amount of time (about 30 minutes) to become ready.
Long-running operations such as
clonecan time out when projects are large or connections outlast the HTTP timeouts of reverse proxies.
The Scala kernel does not support auto-complete features in the editor.
Scala and R code can sometimes indent incorrectly in the workbench editor.
