> Fix Ozone FS listStatus() cache-table inconsistencies.
> ------------------------------------------------------
>
> Key: HDDS-9347
> URL: https://issues.apache.org/jira/browse/HDDS-9347
> Project: Apache Ozone
> Issue Type: Bug
> Components: Ozone Filesystem, Ozone Manager
> Reporter: Sadanand Shenoy
> Assignee: Sadanand Shenoy
> Priority: Major
> Labels: pull-request-available
>
> Ozone Manager records writes first to its cache during any write operation
> and this cache is flushed at regular intervals by the DoubleBuffer daemon.
> A filesystem is expected to be strongly consistent and hence reads that
> follow these writes will hit the cache and the cache has to return the
> correct results.
> The results returned by the cache should be exactly as if the results are
> returned by the table. i.e there shouldn't be any difference in logic while
> processing the reads all from cache vs table.
> Such inconsistencies can cause intermittent failures in reads as reading from
> cache results one result while from the table another.
> This jira aims to solve such cases.
