Subject [jira] [Updated] (HDFS-9410) Fix all HDFS unit tests to correctly reset to sysout and syserr
Date Thu, 12 Nov 2015 20:56:11 GMT

     [ https://issues.apache.org/jira/browse/HDFS-9410?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Xiao Chen updated HDFS-9410:
----------------------------
    Description: 
Originally found in {{TestDFSAdminWithHA#tearDown}} where System.out.flush() throws an NPE.

The cause is that 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 jira tries to fix all similar occurrences of this issue
