Fengnan Li updated HDFS-15196: ------------------------------ Attachment: HDFS-15196.004.patch > RBF: RouterRpcServer getListing cannot list large dirs correctly > ---------------------------------------------------------------- > > Key: HDFS-15196 > URL: https://issues.apache.org/jira/browse/HDFS-15196 > Project: Hadoop HDFS > Issue Type: Bug > Reporter: Fengnan Li > Assignee: Fengnan Li > Priority: Critical > Attachments: HDFS-15196.001.patch, HDFS-15196.002.patch, > HDFS-15196.003.patch, HDFS-15196.003.patch, HDFS-15196.004.patch > > > In RouterRpcServer, getListing function is handled as two parts: > # Union all partial listings from destination ns + paths > # Append mount points for the dir to be listed > In the case of large dir which is bigger than DFSConfigKeys.DFS_LIST_LIMIT > (with default value 1k), the batch listing will be used and the startAfter > will be used to define the boundary of each batch listing. However, step 2 > here will add existing mount points, which will mess up with the boundary of > the batch, thus making the next batch startAfter wrong. > The fix is just to append the mount points when there is no more batch query > necessary. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
