Masatake Iwasaki updated HADOOP-13017: -------------------------------------- Resolution: Fixed Fix Version/s: 3.0.0-alpha2 2.8.0 Status: Resolved (was: Patch Available) Committed. Thanks, [~ste...@apache.org]. > Implementations of InputStream.read(buffer, offset, bytes) to exit 0 if > bytes==0 > -------------------------------------------------------------------------------- > > Key: HADOOP-13017 > URL: https://issues.apache.org/jira/browse/HADOOP-13017 > Project: Hadoop Common > Issue Type: Improvement > Components: io > Affects Versions: 2.8.0 > Reporter: Steve Loughran > Assignee: Steve Loughran > Fix For: 2.8.0, 3.0.0-alpha2 > > Attachments: HADOOP-13017-002.patch, HDFS-13017-001.patch > > > HDFS-10277 showed that HDFS was return -1 on read(buf[], 0, 0) when there was > no data left in the stream; Java IO says > bq. If {{len}} is zero, then no bytes are read and {{0}} is returned; > otherwise, there is an attempt to read at least one byte. > Review the implementations of {{IOStream.(buffer, offset, bytes)} and, where > necessary and considered safe, add a fast exit if the length is 0. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
