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

             Summary: The sleep time in checkQuota of replication WAL reader 
should be controlled independently 
                 Key: HBASE-27881
                 URL: https://issues.apache.org/jira/browse/HBASE-27881
             Project: HBase
          Issue Type: Improvement
          Components: Replication
    Affects Versions: 2.5.4, 3.0.0-alpha-3
            Reporter: Xiaolin Ha
            Assignee: Xiaolin Ha


In theory the sleep time when checking quota failed in replication WAL reader 
should match the consume ability of the memory. But at the very least we should 
isolate the configuration here with the sleep time for common circumstances 
when replicating, e.g. sleep before reading from the head of the WAL, to avoid 
a little bit bigger sleep time(e.g. 3s) making consume speed always blocked by 
checking quota.
