> Reduce unnecessary getFileStatus hdfs calls in TTL hfile and hlog cleanners

> Key: HBASE-8690
> URL: https://issues.apache.org/jira/browse/HBASE-8690
> Project: HBase
> Issue Type: Improvement
> Components: master
> Reporter: Liu Shaohui
> Priority: Minor
> Attachments: 8690-trunk-v3.patch, 8690-trunk-v4.patch,

>
> For each in file in archive dir, the TimeToLiveHFileCleaner need call
> getFileStatus to get the modify time of file. Actually the CleanerChore have
> had the file status when listing its parent dir.
> When we set the TTL to 7 days in our cluster for data security, the number of
> files left in archive dir is up to 65 thousands. In each clean period,
> TimeToLiveHFileCleaner will generate ten thousand getFileStatus call in a
> short time, which is very heavy for hdfs namenode.
> Fix: Change the path param to FileStatus in isFileDeletable method and reduce
> unnecessary getFileStatus hdfs calls in TTL cleaners.
