Subject [jira] Updated: (HBASE-1309) HFile catches key in Memcache with empty value
Date Sun, 05 Apr 2009 03:31:12 GMT

     [ https://issues.apache.org/jira/browse/HBASE-1309?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Andrew Purtell updated HBASE-1309:
----------------------------------

    Summary: HFile catches key in Memcache with empty value  (was: HFile$Writer.checkValue:
IOException: Value cannot be null or empty)

Changed issue title after some initial digging in the code. 

Null values is one thing. Should empty values just be ignored rather than cause exceptions?
