Subject [jira] [Updated] (HBASE-7106) [89-fb] Fix the NPE in unit tests for JDK7
Date Tue, 06 Nov 2012 22:34:12 GMT

     [ https://issues.apache.org/jira/browse/HBASE-7106?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Liyin Tang updated HBASE-7106:
------------------------------

    Description: 
In JDK7, it will throw out NPE if put a NULL into a TreeSet. And in the unit tests, user can
add a NULL as qualifier into the family map for GET or SCAN. 
So we shall do the followings: 

1) Make sure the semantics of NULL column qualifier is equal to that of the EMPYT_BYTE_ARRAY
column qualifier.

2) An easy fix is to use the EMPYT_BYTE_ARRAY qualifier to replace NULL qualifier in the family
map for the GET or SCAN objects, and everything else shall be backward compatible.

3) Add a jdk option in the pom.xml (Assuming user installed the fb packaged jdk)
eg: mvn test -Dtest=TestFromClientSide -Pjdk7
