> DFSInputStream to prefer cached replica
> ---------------------------------------
>
> Key: HDFS-14283
> URL: https://issues.apache.org/jira/browse/HDFS-14283
> Project: Hadoop HDFS
> Issue Type: Improvement
> Affects Versions: 2.6.0
> Environment: HDFS Caching
> Reporter: Wei-Chiu Chuang
> Assignee: Lisheng Sun
> Priority: Major
> Attachments: HDFS-14283.001.patch, HDFS-14283.002.patch,
> HDFS-14283.003.patch, HDFS-14283.004.patch, HDFS-14283.005.patch,

>
> HDFS Caching offers performance benefits. However, currently NameNode does
> not treat cached replica with higher priority, so HDFS caching is only useful
> when cache replication = 3, that is to say, all replicas are cached in
> memory, so that a client doesn't randomly pick an uncached replica.
> HDFS-6846 proposed to let NameNode give higher priority to cached replica.
> Changing a logic in NameNode is always tricky so that didn't get much
> traction. Here I propose a different approach: let client (DFSInputStream)
> prefer cached replica.
> A {{LocatedBlock}} object already contains cached replica location so a
> client has the needed information. I think we can change
> {{DFSInputStream#getBestNodeDNAddrPair()}} for this purpose.
