Subject [jira] [Commented] (ACCUMULO-1032) encryption changes break diagnostic LogReader
Date Mon, 04 Feb 2013 15:06:13 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-1032?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13570317#comment-13570317
] 

Eric Newton commented on ACCUMULO-1032:
---------------------------------------

Reading the magic in the new format might be broken.  It does not protect against some crazy
initial value from the old log file format, which might cause it to read the entire file as
a single UTF string.
