             Summary: Fix SSTable descriptor mismatch preventing newly produced SSTables from being uploaded
                 Key: CASSANALYTICS-98
                 URL: https://issues.apache.org/jira/browse/CASSANALYTICS-98
             Project: Apache Cassandra Analytics
          Issue Type: Bug
          Components: Writer
            Reporter: Yifan Cai
            Assignee: Yifan Cai


The bug was in SSTables.getSSTableBaseName() which included a trailing dash (e.g., "oa-1-big-") while SSTable descriptors created during production didn't have the trailing dash (e.g., "oa-1-big"). This mismatch caused the filter in SortedSSTableWriter.prepareSStablesToSend() to exclude all newly produced SSTables from upload, as the descriptors never matched.

The fix removes the trailing dash by changing lastIndexOf("-") + 1 to lastIndexOf("-") and adds corresponding logic to avoid double-hashing already-streamed SSTables.

The bug does not cause data loss. All produced sstables are still uploaded when the writer is closed. The bugs is causing the delay of sending those files, as they could have been sent when they are just produced. I believe the bug was introduced in CASSANALYTICS-5.
