----------------------------

             Summary: Allow lease recovery for multiple paths to be issued in one request
                 Key: HDFS-4642
                 URL: https://issues.apache.org/jira/browse/HDFS-4642
             Project: Hadoop HDFS
          Issue Type: Bug
            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.
