Staffan Friberg created HDFS-10620:
--------------------------------------
Summary: StringBuilder created and appended even if logging is
disabled
Key: HDFS-10620
URL: https://issues.apache.org/jira/browse/HDFS-10620
Project: Hadoop HDFS
Issue Type: Bug
Components: namenode
Affects Versions: 2.6.4
Reporter: Staffan Friberg
In BlockManager.addToInvalidates the StringBuilder is appended to during the
delete even if logging isn't active.
Could avoid allocating the StringBuilder as well, but not sure if it is really
worth it to add null handling in the code.
