Mukul Kumar Singh commented on HADOOP-15074:
--------------------------------------------
Hi [[email protected]], Yes, the length of the file wasn't updated after a
hsync/hflush on the writer. This happens because the update length isn't passed
as part of the flush/sync. Hence the length isn't updated as part of the sync
request.
{code}
@Override
public void hsync() throws IOException {
try (TraceScope ignored = dfsClient.newPathTraceScope("hsync", src)) {
flushOrSync(true, EnumSet.noneOf(SyncFlag.class));
}
}
{code}
> SequenceFile#Writer flush does not update the length of the written file.
