Todd Lipcon commented on HDFS-4642:
-----------------------------------
Why not just use a threadpool on the client to issue them in parallel? It
doesn't seem like there is a lot of work to be amortized on the server side
here.
> 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: 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.
