Todd Lipcon commented on HDFS-3765:
-----------------------------------
Seems it's not passing its unit tests. I think the code needs to look like this
instead:
{code}
newSharedEditLog.logEdit(op);
if (op.opCode == FSEditLogOpCodes.OP_END_LOG_SEGMENT) {
newSharedEditLog.endCurrentLogSegment(true);
break;
}
{code}
Otherwise the END_LOG_SEGMENT transaction doesn't end up logged in shared
edits, and you end up with a one-op gap in between every segment.
