------------------------------------------
Summary: Option to disable auto-formatting and type detection in
table displays
Key: ZEPPELIN-1760
URL: https://issues.apache.org/jira/browse/ZEPPELIN-1760
Project: Zeppelin
Issue Type: Wish
Components: front-end, GUI
Affects Versions: 0.6.2
Reporter: Everett Anderson
Support disabling auto-format/type detection of table displays.
ZEPPELIN-1371 added auto-format/type detection table displays. For example,
when Zeppelin believes a given column contains numbers (even if it were, say, a
Spark DataFrame string column) it displays these in the UI with commas.
However, this can be misleading in some workflows. For example, when using
Zeppelin to evaluate a table produced by an extraction pipeline for a
fixed-width or CSV file, it can be important to know how many characters were
in the field. Maybe more commonly, sometimes columns are not numbers but codes.
It'd be great to have the ability to configure column type detection and
display format.
Disabling automatic type detection/format globally or per interpreter in
configuration would be a first step. At the moment, I don't believe there's a
way to see the "true" column values in a table.
