-----------------------------
Summary: The dncp_block_verification log can be compressed
Key: HDFS-4224
URL: https://issues.apache.org/jira/browse/HDFS-4224
Project: Hadoop HDFS
Issue Type: Improvement
Components: data-node
Affects Versions: 2.0.0-alpha
Reporter: Harsh J
Priority: Minor
On some systems, I noticed that when the scanner runs, the
dncp_block_verification.log.curr file under the block pool gets quite large
(several GBs). Although this is rolled away, we could also configure
compression upon it (a codec that may work without natives, would be a good
default) and save on I/O and space.
