Tool to look at HLogs -- parse and tail -f
------------------------------------------
Key: HBASE-2889
URL: https://issues.apache.org/jira/browse/HBASE-2889
Project: HBase
Issue Type: Bug
Components: wal
Reporter: stack
Assignee: stack
Fix For: 0.90.0
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.
