> Project: HBase
> Issue Type: Bug
> Components: HFile, mapreduce
> Reporter: selina.yan

> When HFileOutputFormat2 is used to create an hfile, the CREATE_TIME_TS of
> hfileinfo will not be assigned when creating an hfileContext, resulting in
> the value of lastMajorCompactionAge is the timestamp of the current time.
