> Remove synchronized input streams from Writable deserialization
> ---------------------------------------------------------------
>
> Key: HADOOP-10694
> URL: https://issues.apache.org/jira/browse/HADOOP-10694
> Project: Hadoop Common
> Issue Type: Bug
> Components: io
> Reporter: Gopal V
> Assignee: Gopal V
> Labels: BB2015-05-TBR
> Attachments: HADOOP-10694.1.patch, HADOOP-10694.2.patch,
> writable-read-sync.png
>
>
> Writable deserialization is slowing down due to a synchronized block within
> DataInputBuffer$Buffer.
> ByteArrayInputStream::read() is synchronized and this shows up as a slow
> uncontested lock.
> Hive ships with its own faster thread-unsafe version with
> hive.common.io.NonSyncByteArrayInputStream.
> !writable-read-sync.png!
> The DataInputBuffer and Writable deserialization should not require a lock
> per readInt()/read().
