Subject [jira] [Created] (HADOOP-13163) Reuse pre-computed filestatus in Distcp-CopyMapper
Date Tue, 17 May 2016 04:35:13 GMT
Rajesh Balamohan created HADOOP-13163:

             Summary: Reuse pre-computed filestatus in Distcp-CopyMapper
                 Key: HADOOP-13163
                 URL: https://issues.apache.org/jira/browse/HADOOP-13163
             Project: Hadoop Common
          Issue Type: Bug
            Reporter: Rajesh Balamohan


targetStatus is already computed and it can be reused in checkUpdate() function. This wouldn't
be a major issue in NN/HDFS, but in the case of S3 getFileStatus calls can be expensive.
