>                 Key: HDFS-4642
>                 URL: https://issues.apache.org/jira/browse/HDFS-4642
>             Project: Hadoop HDFS
>          Issue Type: Improvement
>            Reporter: Ted Yu
>
> Currently client can only request lease recovery for one Path:
> {code}
>   public boolean recoverLease(Path f) throws IOException {
> {code}
> For HBase distributed log splitting, Nicolas made a suggestion here:
> https://issues.apache.org/jira/browse/HBASE-7878?focusedCommentId=13615364&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13615364
> HBase master collects the files that should be split, it issues lease recovery for the
files (in one request), then distribute log splitting.
> This would help shorten MTTR.
