> Tailing a file involves reopening it for each seek, so for example when running replication
it looks like this every time:
> {noformat}
> 2013-08-28 21:45:00,205 DEBUG [regionserver60020-EventThread.replicationSource,1] org.apache.hadoop.hbase.fs.HFileSystem:
/hbase-master/WALs/jdec2hbase0403-5,60020,1377724981186/jdec2hbase0403-5%2C60020%2C1377724981186.1377725847406
is an HLog file, so reordering blocks, last hostname will be:jdec2hbase0403-5
> 2013-08-28 21:45:00,211 DEBUG [regionserver60020-EventThread.replicationSource,1] org.apache.hadoop.hbase.regionserver.wal.ProtobufLogReader:
After reading the trailer: walEditsStopOffset: 0, fileLength: 0, trailerPresent: false
> {noformat}
> The frequency makes it more relevant for TRACEing.
