Xiaoqiao He updated HDFS-17462: ------------------------------- Summary: RBF: NPE in Router concat when trg is an empty file. (was: NPE in Router concat when trg is an empty file.) > RBF: NPE in Router concat when trg is an empty file. > ---------------------------------------------------- > > Key: HDFS-17462 > URL: https://issues.apache.org/jira/browse/HDFS-17462 > Project: Hadoop HDFS > Issue Type: Bug > Affects Versions: 2.10.2, 3.3.6 > Reporter: NaihaoFan > Priority: Minor > Labels: pull-request-available > > When trg of Router concat is an empty file, it will trigger NPE in Router, > and the concat will fail, example: > This is because when trg is an empty file, NameNode will return > lastLocatedBlock as null in the response of getBlockLocations. And Router > will not check null of lastLocatedBlock returned, instead Router will use it > to get block pool id directly. > Trg of concat is an empty file should be allowed in router since this case is > supported by concat of NameNode. -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
