Javier Vega created HUDI-528:
--------------------------------
Summary: Incremental Pull fails when latest commit is empty
Key: HUDI-528
URL: https://issues.apache.org/jira/browse/HUDI-528
Project: Apache Hudi (incubating)
Issue Type: Bug
Components: Incremental Pull
Reporter: Javier Vega
When trying to create an incremental view of a dataset, an exception is thrown
when the latest commit in the time range is empty. In order to determine the
schema of the dataset, Hudi will grab the [latest commit file, parse it, and
grab the first metadata file
path|[https://github.com/apache/incubator-hudi/blob/480fc7869d4d69e1219bf278fd9a37f27ac260f6/hudi-spark/src/main/scala/org/apache/hudi/IncrementalRelation.scala#L78-L80]].
If the latest commit was empty though, the field which is used to determine
file paths (partitionToWriteStats) will be empty causing the following
exception:
