--------------------------------------------
Summary: HBase Shell "delete" command can cause older versions to
be shown even if VERSIONS is configured as 1
Key: HBASE-21596
URL: https://issues.apache.org/jira/browse/HBASE-21596
Project: HBase
Issue Type: Bug
Reporter: Wellington Chevreuil
Assignee: Wellington Chevreuil
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.
