Vinayakumar B created HDFS-7210: ----------------------------------- Summary: Avoid two separate RPC's namenode.append() and namenode.getFileInfo() for an append call from DFSClient Key: HDFS-7210 URL: https://issues.apache.org/jira/browse/HDFS-7210 Project: Hadoop HDFS Issue Type: Improvement Reporter: Vinayakumar B Assignee: Vinayakumar B
Currently DFSClient does 2 RPCs to namenode for an append operation. {{append()}} for re-opening the file and getting the last block, {{getFileInfo()}} Another on to get HdfsFileState If we can combine result of these 2 calls and make one RPC, then it can reduce load on NameNode. For the backward compatibility we need to keep existing {{append()}} call as is, need to add one more. similar to {{rename2}} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
