-----------------------------------------
Summary: Reduce memory copy in
BlobOutputStreamInternal::dispatchWrite
Key: HADOOP-14612
URL: https://issues.apache.org/jira/browse/HADOOP-14612
Project: Hadoop Common
Issue Type: Sub-task
Components: fs/azure
Reporter: Rajesh Balamohan
Priority: Minor
Currently in {{BlobOutputStreamInternal::dispatchWrite}}, buffer is copied
internally for every write. During large uploads this can be around 4 MB. This
can be avoided if there is internal class which extends ByteArrayOutputStream
with additional method "ByteArrayInputStream getInputStream()".
