Harsh J reassigned HDFS-2263: ----------------------------- Assignee: (was: Harsh J) > Make DFSClient report bad blocks more quickly > --------------------------------------------- > > Key: HDFS-2263 > URL: https://issues.apache.org/jira/browse/HDFS-2263 > Project: Hadoop HDFS > Issue Type: Improvement > Components: hdfs-client > Affects Versions: 0.20.2 > Reporter: Aaron T. Myers > Priority: Major > Attachments: HDFS-2263.patch > > > In certain circumstances the DFSClient may detect a block as being bad > without reporting it promptly to the NN. > If when reading a file a client finds an invalid checksum of a block, it > immediately reports that bad block to the NN. If when serving up a block a DN > finds a truncated block, it reports this to the client, but the client merely > adds that DN to the list of dead nodes and moves on to trying another DN, > without reporting this to the NN. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
