--------------------------------------
Summary: [0.98] NoTagsKeyValue optimization is not proper
Key: HBASE-13807
URL: https://issues.apache.org/jira/browse/HBASE-13807
Project: HBase
Issue Type: Bug
Reporter: Anoop Sam John
Assignee: Anoop Sam John
Fix For: 0.98.14
When the file format is V2, it has no support for tags and so cells will be
with 0 tags length. For such cells we make NoTagsKeyValue which avoid
getTagsLength parsing overhead in KeyValue. Still HFileReaderV2 creates
KeyValue.
This is a 0.98 issue only.
Also in case of DBE, we can consider the tags length and return
KeyValue/NoTagsKeyValue
