Subject [jira] [Updated] (HDFS-12949) Fix findbugs warning in ImageWriter.java
Date Wed, 20 Dec 2017 14:03:03 GMT

     [ https://issues.apache.org/jira/browse/HDFS-12949?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Akira Ajisaka updated HDFS-12949:
---------------------------------
    Attachment: HDFS-12949.001.patch

HDFS-12903 added findbugs-exclude.xml to ignore the warning, however, it is not sufficient.
We need to add a setting in pom.xml to use the findbugs-exclude.xml.
