David Mollitor created HDFS-14641: ------------------------------------- Summary: Possible Intermediate Block Report Race Condition Key: HDFS-14641 URL: https://issues.apache.org/jira/browse/HDFS-14641 Project: Hadoop HDFS Issue Type: Bug Affects Versions: 3.2.0 Reporter: David Mollitor
I am doing some playing around in the DataNode and if I set a small delay (100ms) before sending the intermediate block reports, the file files to transfer. This is a one-node cluster with a tiny file. Here is the output from the NameNode: {code:none} 2019-07-09 20:45:37,198 INFO namenode.FSNamesystem: BLOCK* blk_1073741829_1005 is COMMITTED but not COMPLETE(numNodes= 0 < minimum = 1) in file /tmp/sent.12.data._COPYING_ 2019-07-09 20:45:37,606 INFO namenode.FSNamesystem: BLOCK* blk_1073741829_1005 is COMMITTED but not COMPLETE(numNodes= 0 < minimum = 1) in file /tmp/sent.12.data._COPYING_ 2019-07-09 20:45:38,413 INFO namenode.FSNamesystem: BLOCK* blk_1073741829_1005 is COMMITTED but not COMPLETE(numNodes= 1 >= minimum = 1) in file /tmp/sent.12.data._COPYING_ 2019-07-09 20:45:40,023 INFO namenode.FSNamesystem: BLOCK* blk_1073741829_1005 is COMMITTED but not COMPLETE(numNodes= 1 >= minimum = 1) in file /tmp/sent.12.data._COPYING_ {code} If I setup a thread that watches for IBRs and send them to the NN immediately, the file transfers successfully. There may be a race condition here. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-dev-h...@hadoop.apache.org
