we debugged the code and added 'try-catch' around the following codes in
FSEditLog.java to skip error inodefiles.
INodeFile node = null;
try {
node =
(INodeFile) fsDir.unprotectedAddFile(path, permissions,
blocks,
replication, mtime, atime, blockSize);
} catch (Exception e) {
FSNamesystem.LOG.warn("INode error, " + e);
break;
}
Finally, we skiped 6791 operations, most of them are rename and setTimes,
and lost log data for 1 day, but hbase's data are not corrupted. The 6.3GB
edits.new file has been replayed into the 14MB fsimage.
