-----------------------------------
Labels: pull-request-available (was: )
> Preserve sparse rows when pruning columns in Spark 4 reads
> ----------------------------------------------------------
>
> Key: HBASE-30512
> URL: https://issues.apache.org/jira/browse/HBASE-30512
> Project: HBase
> Issue Type: Sub-task
> Components: hbase-connectors
> Reporter: mazhengxuan
> Priority: Major
> Labels: pull-request-available
>
> Restricting a Scan or Get to projected qualifiers may drop a sparse HBase row
> when those qualifiers are absent, even though the row has data in other
> columns. For example, selecting the row key and a missing qualifier should
> return the row with null rather than omit it.
> We should first add end-to-end tests for both Scan and Get, then adjust
> column pruning to preserve row existence, covering missing qualifiers
> separately from present cells with empty values.
