Log Splitting & Replay: Distinguish between Network IOE and Parsing IOE
-----------------------------------------------------------------------

                 Key: HBASE-3081
                 URL: https://issues.apache.org/jira/browse/HBASE-3081
             Project: HBase
          Issue Type: Bug
          Components: io, master, regionserver, replication
    Affects Versions: 0.89.20100924, 0.90.0
            Reporter: Nicolas Spiegelberg
            Assignee: Nicolas Spiegelberg
             Fix For: 0.89.20100924, 0.90.0


Originally, if HBase got an IOE from HDFS while splitting or opening a region, it would abort
the operation. The assumption being that this is a network failure that will likely disappear
at a later time or different partition of the network. However, if HBase gets parsing exceptions,
we want to log the problem and continue opening/splitting the region anyways, because parsing
is an idempotent problem and retries won't fix this issue.
