A very short article and precisely focusing on the problem of trimmed string in the cell value on Zeppelin tool.
For those, who don’t know what zeppelin is, its web interactive tool, which helps to run scala / sql on spark cluster directly.
Recently, we found a simple issue, where team reported, long string values were getting trimmed, while querying in zeppelin.
After a bit of R&D, we found its just a simple config on Livy interpreter, which enables / disables this behavior.
If we try with simple query on zeppelin, where the string length is big, it will trim the string in the result as shown below.
After setting the property ” zeppelin.livy.spark.sql.field.truncate” as false through the interpreter (Livy2) settings, This worked like a charm.
For setting this
1. Go to the interpreter
2. Click on EDIT for Livy2 interpreter
3. Adding this property and save, it will ask for a restart while saving.
Next time, when you open your notebook and run the same query, it will work as below.
Hope, you learned something with this small article !!!
