> 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
> 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.
