---------------------------------------
Summary: TxnLogToolkit uses Scanner badly
Key: ZOOKEEPER-3039
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3039
Project: ZooKeeper
Issue Type: Bug
Reporter: Andor Molnar
Assignee: Andor Molnar
If more than 1 CRC error is found in the Txn log file, TxnLogToolkit fails to
get an answer for the second one, because it has already closed the Scanner
which was probably closed the input stream also, so exception is thrown:
