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

             Summary: make initial sleeptime in locateFollowingBlock configurable for DFSClient.
                 Key: HDFS-7835
                 URL: https://issues.apache.org/jira/browse/HDFS-7835
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: dfsclient
            Reporter: zhihai xu
            Assignee: zhihai xu


Make initial sleeptime in locateFollowingBlock configurable for DFSClient.
Current the sleeptime/localTimeout in locateFollowingBlock/completeFile from DFSOutputStream is hard-coded as 400 ms, but retries can be configured by "dfs.client.block.write.locateFollowingBlock.retries". We should also make the initial sleeptime configurable to give user more flexibility to control both retry and delay.
