Walter Su commented on HDFS-9410: --------------------------------- I didn't see TestDFSAdminWithHA failed these days. So this jira is for precaution, to fix error-prone code, do you mind fix all these places(maybe more than those listed above) together? > TestDFSAdminWithHA#tearDown may throw NPE > ----------------------------------------- > > Key: HDFS-9410 > URL: https://issues.apache.org/jira/browse/HDFS-9410 > Project: Hadoop HDFS > Issue Type: Test > Components: HDFS > Reporter: Xiao Chen > Assignee: Xiao Chen > Priority: Minor > Attachments: HDFS-9410.001.patch, HDFS-9410.002.patch > > > If for any reason {{setUpHaCluster}} fails before storing {{System.out}} and > {{System.err}} as member variables {{originOut}} and {{originErr}}, then in > {{tearDown}} {{System.out}} and {{System.err}} are set to null. This could > cause all following tests to fail when calling {{flush}}. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
