Which Delta project/connector is this regarding?

  • Spark
  • Standalone
  • Flink
  • Kernel
  • Docs update

Description

This PR adds a Troubleshooting: Delta Storage dependency error section to delta-storage docs explaining the common java.lang.NoClassDefFoundError: io/delta/storage/LogStore failure when Delta Storage is missing from the Spark classpath.
It documents:

  • A concrete example stack trace for the missing LogStore error.
  • Why this happens when users supply a locally built delta-spark JAR via --jars and transitive deps (like delta-storage) are not pulled in and
  • How to fix the issue

This is a doc update related to bug #5531

How was this patch tested?

Made the changes and tested the changes locally using npm
image

Does this PR introduce any user-facing changes?

Yes.
Before: Users hitting NoClassDefFoundError: io/delta/storage/LogStore had no dedicated troubleshooting guidance in the delta-storage docs. Now the storage configuration page would have a section called Troubleshooting Delta Storage dependency error which explains the root cause and the fix .
