Subject [jira] Commented: (CASSANDRA-377) Cannot get_slice from CF defined with CompareWith="TimeUUIDType"
Date Wed, 19 Aug 2009 02:05:14 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-377?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12744843#action_12744843
] 

Evan Weaver commented on CASSANDRA-377:
---------------------------------------

if I send nil:

<CassandraThrift::SlicePredicate slice_range:<CassandraThrift::SliceRange start:nil,
finish:nil, reversed:false, count:100>>

I get:

ERROR - Internal error processing get_slice
java.lang.NullPointerException
	at org.apache.cassandra.db.marshal.TimeUUIDType.getString(TimeUUIDType.java:46)
	at org.apache.cassandra.db.SliceFromReadCommand.toString(SliceFromReadCommand.java:71)
	at java.lang.String.valueOf(String.java:2827)
	at java.lang.StringBuilder.append(StringBuilder.java:115)
