> Key: HUDI-6154
> URL: https://issues.apache.org/jira/browse/HUDI-6154
> Project: Apache Hudi
> Issue Type: Bug
> Reporter: Prashant Wason
> Assignee: Prashant Wason
> Priority: Major
> Labels: pull-request-available
>
> When a process wants to update hoodie.properties, it follows these steps:
> # Read hoodie.properties
> # Create hoodie.properties.backup
> # Write properties read in #1 into hoodie.properties.backup
> # Delete hoodie.properties
> # Create hoodie.properties
> # Write updated properties into hoodie.properties
> # Delete hoodie.properties.backup
> The reader has this mechanism:
> # Read hoodie.properties.
> # If not found, read hoodie.properties.backup
> In case of a race between reader and writer, reader may read
> hoodie.properties after step #4 (hoodie.properties deleted by writer) and
> then try to read hoodie.properties.backup after step #7
> (hoodie.properties.backup deleted by writer). The reader will assume that
> hoodie.properties does not exist and throw an error.
> To deal with this a retry is introduced.
