The fsck is showing you an average block size, not the block size
metadata attribute of the file like stat shows. In this specific case,
the average is just the length of your file, which is lesser than one
whole block.

Hi there,
I am trying to customize the log format of containers, as a first step I

log4j.appender.CLA.layout.ConversionPattern located in the container's
classpath. Tthe result is that the syslog file is written to:
Thanks for your comments!
As I mentioned HDFS use only what it needs on the local file system. For
example, a 16 KB hdfs file only use 16 KB local file system storage, not 64

The block size is a meta attribute. If you append to the file later,
it still needs to know when to split further - so it keeps that value
as a mere metadata it can use to advise itself on write boundaries.

This is intentional, and only within MR2's scope - we do not support
configuring the formatting, but do support switching the levels (via
job properties). You should still be able to customise your own YARN
apps' logging configuration though.
