[jira] [Commented] (ZOOKEEPER-1520) A txn log record with a corrupt
sentinel byte looks like EOF
[ https://issues.apache.org/jira/browse/ZOOKEEPER-1520?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13426199#comment-13426199 ]
Patrick Hunt commented on ZOOKEEPER-1520:
-----------------------------------------
"ant test" is usually how we do it.
Also "ant eclipse" and then open the project in eclipse itself.
No need to download jars and such (slf/log/etc..) those will be d/l automatically by ant.

> In Util.readTxnBytes() the sentinel is compared with 0x42 and if it does not match then the record is considered partially written and thus the EOF. However if it is a partial record the sentinel should be 0x00 since that is what the log is initialized with. Any other value would indicate corruption and should throw an IOException rather than indicate EOF. See [ZOOKEEPER-1453|https://issues.apache.org/jira/browse/ZOOKEEPER-1453] for a related issue.
