dhruba borthakur commented on HDFS-3051: ---------------------------------------- The new API can be a new method in FSDataInputStream. {code} public List<ByteBuffer> readFullyScatterGather(long position, int length) throws IOException { return ((PositionedReadable)in).readFullyScatterGather(position, length); } {code} This will allow an application to read multiple sections of the file at the same time. It will also allow HDFS to return mapped byte buffers or direct byte buffers. > A zero-copy read api from FSDataInputStream > ------------------------------------------- > > Key: HDFS-3051 > URL: https://issues.apache.org/jira/browse/HDFS-3051 > Project: Hadoop HDFS > Issue Type: Improvement > Components: hdfs client > Reporter: dhruba borthakur > > It will be nice if we can get a new API from FSDtaInputStream that allows for > zero-copy read for hdfs readers. -- This message is automatically generated by JIRA.
