      Description

      Currently client can only request lease recovery for one Path:

        public boolean recoverLease(Path f) throws IOException {
      

      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.
