--------------------------
Resolution: Later
Resolving. Old. When HDFS has a tail, we'll make an issue to implement tail of
WAL
> Tool to look at HLogs -- parse and tail -f

> We need a tool for looking at wals. A tail -f would be sweet though it might
> be ugly having to open each time it wants to dump next lot of edits out wal
> log.
> From Kannan:
> {code}20:45 <kannan> WALEdit already has a toString().
> 20:46 <kannan> And append/sync support allows you to read concurrently a file
> that is being written too... (like JDs replication).
> 20:46 <kannan> So it would be good if I could do a bin/hbase hlogprint -f
> hdfs://...../.logs/<filename> -v -p
> 20:46 <kannan> much like the HFile pretty printer... except the HLog one is
> effectively a tail -f.
> {code}
