Subject [jira] [Commented] (HDFS-11696) Fix warnings from Spotbugs in hadoop-hdfs
Date Thu, 11 May 2017 21:15:04 GMT

    [ https://issues.apache.org/jira/browse/HDFS-11696?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16007208#comment-16007208

Akira Ajisaka commented on HDFS-11696:

Thank you for updating the patch, [~linyiqun]. Can we just ignore the warnings in NNUpgradeUtil.java
by adding a section in findbugs-exclude.xml? The method throws NPE even after the fix when
the input variable is null.
