---------------------------------
Summary: Increase the default block size
Key: HDFS-4053
URL: https://issues.apache.org/jira/browse/HDFS-4053
Project: Hadoop HDFS
Issue Type: Improvement
Reporter: Eli Collins
The default HDFS block size ({{dfs.blocksize}}) has been 64mb forever. 128mb
works well in practice on today's hardware configurations, most clusters I work
with use it or higher (eg 256mb). Let's bump to 128mb in trunk for v3.
