Resolution: Duplicate
Tracked in HDFS-1861.

> Key: HADOOP-5177
> URL: https://issues.apache.org/jira/browse/HADOOP-5177
> Project: Hadoop Common
> Issue Type: Bug
> Reporter: Nathan Marz
>
> On our cluster, unless we manually increase the number of xcievers via the
> property dfs.datanode.max.xcievers, our jobs fail with the typical exception
> being "Could not get block locations...". We have the xcievers property set
> to 8000 now which resolved the issue for us. Clearly, the Hadoop default
> should be much higher than what it is now (256 I believe).
