>
> HBase Shell delete command is supposed to operate over an specific TS. If no
> TS is informed, it will assume the latest TS for the cell and put delete
> marker for it.
> However, for a CF with VERSIONS => 1, if multiple puts were performed for
> same cell, there may be multiple cell versions on the memstore, so delete
> would only be "delete marking" one of those, and causing the most recent no
> marked one to be shown on gets/scans, which then contradicts the CF "VERSIONS
> => 1" configuration.
> This issue is not seen with deleteall command or using Delete operation from
> Java API.
