HBASE-551 Master stuck splitting server logs in shutdown loop;
on eachiteration, edits are aggregated up into the millions
M src/java/org/apache/hadoop/hbase/HLog.java
    (splitLog): If an exception processing a split, catch it.
    In finally, close and delete the split. Don't try retrying.
    While in some circumstance, we might recover, its also
    likely that we just get same exception again. If so, and
    multiple files, we'll just accumulate edits until the
    kingdom comes.
