Ted Yu created HDFS-4642:
----------------------------
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.
