[jira] [Updated] (HBASE-8449) Refactor recoverLease retries and pauses informed by findings over in hbase-8389

     [ https://issues.apache.org/jira/browse/HBASE-8449?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

stack updated HBASE-8449:
-------------------------

    Description: 
HBASE-8359 is an interesting issue that roams near and far.  This issue is about making use of the findings handily summarized on the end of hbase-8359 which have it that trunk needs refactor around how it does its recoverLease handling (and that the patch committed against HBASE-8359 is not what we want going forward).

This issue is about making a patch that adds a lag between recoverLease invocations where the lag is related to dfs timeouts -- the hdfs-side dfs timeout -- and optionally makes use of the isFileClosed API if it is available (a facility that is not yet committed to a branch near you and unlikely to be within your locality with a good while to come).
