[jira] [Commented] (TEPHRA-243) When transaction log sync is slow,
the warning message should contain more information
[ https://issues.apache.org/jira/browse/TEPHRA-243?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16159695#comment-16159695 ]

---------------------------------------
GitHub user anew opened a pull request:
https://github.com/apache/incubator-tephra/pull/53
(TEPHRA-243) Improve logging for slow log append
- adds more detail to the log message (number of entries, bytes written)
- ensures only one thread logs the message concurrently, by moving it into the method actually writes to storage. Previously all threads logged it even if they did not write themselves
- changed ThriftTransactionSystemTest to use LocalTransactionLog (otherwise it does not get tested at all)
- fixed a few unrelated compiler warning encountered on the way
