> Allow setting block locations when opening streams
> --------------------------------------------------
>
> Key: HDFS-17593
> URL: https://issues.apache.org/jira/browse/HDFS-17593
> Project: Hadoop HDFS
> Issue Type: Improvement
> Reporter: Csaba Ringhofer
> Priority: Major
> Labels: pull-request-available
>
> The HDFS client seems to always get block locations from the namenode when
> opening a file:
> https://github.com/apache/hadoop/blob/4525c7e35ea22d7a6350b8af10eb8d2ff68376e7/hadoop-hdfs-project/hadoop-hdfs-client/src/main/java/org/apache/hadoop/hdfs/DFSClient.java#L1099
> This leads to unnecessary RPCs in Apache Impala when doing reads, as the
> block locations are cached globally and the executors already have a good
> guess about the block locations when opening a stream. Unless the cached
> block locations are stale ideally no RPC should be made to the namenode.
