> Project: HBase
> Issue Type: Bug
> Components: Coprocessors
> Affects Versions: 3.0.0, 2.0.0, 2.1.1
> Reporter: Nihal Jain

> *Steps to reproduce*
> 1) Create a region coprocessor an override {{preBatchMutate}} such that it
> create a put corresponding to a user put having same timestamp and TTL as the
> user put.
> 2) Create a table and add a row having TTL set to 3000 ms
> 3) Wait for > 3000 ms
> 4) Scan the table.
> *Result*
> User row is not retreived while put created via coprocessor is still
> retreived.
> *Analysis/Issue*
> Unlike user mutations, the mutations added by coprocessor do not have tags
> corresponding to TTL, hence they retreived even after TTL expires.
