[jira] Updated: (CASSANDRA-1620) statistics not created after
streaming data
Posted by "Jonathan Ellis (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/CASSANDRA-1620?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jonathan Ellis updated CASSANDRA-1620:
--------------------------------------
Attachment: 1620.txt
patch to avoid NPEs when stats file does not exist (upgrading from 0.6).
should still add stats to post-stream build operation since we're iterating through the data file to build the index anyway.
