Re: HDFS sink leaves .tmp files

I'm still seeing this consistently every 24 hour period. Does this sound
like a configuration issue, an issue with the Exec source, or an issue with
the HDFS sink?

Thanks!

I have the same problem. I roll every 1 minute so I have tons of those .tmp
files.

Chris, Eran, this appears to be FLUME-1238, which was fixed in
Flume-1.2.0. Can you let me know if you are using Flume-1.2.0?

Thanks, Kathleen

Re: HDFS sink leaves .tmp files

Chris Neal 2012-09-10, 18:59

I'm using a combination :)

The application tier is 1.3.0-SNAPSHOT
The HDFS tier is CentOS, and I grabbed the latest (at the time) from the
CDH repo. It's version is: 1.1.0+121-1.cdh4.0.1.p0.1.el6

If the issue is on the HDFS sink side, that it could definitely be in my
version!
I'll check if Cloudera has a more recent version to update to.

Thanks!
Chris

Just checked, and from Cloudera, 1.1.0+121-1.cdh4.0.1.p0.1.el6 is still the
latest from their yum repo.

Yeah - that's built against CDH3 though. But I think it would work anyway.

[Moving to [EMAIL PROTECTED] |
https://groups.google.com/a/cloudera.org/group/cdh-user/topics since
this is getting to be CDH specific]
bcc: [EMAIL PROTECTED]

Chris,

When the file has not been closed by the client, the file size may be
shown as 0. The NameNode will not update the metadata about the file
until the block is completed or the file handle is closed. Even if it
updates at a block boundary, the size won't be accurate until the file
is closed.

The metadata takes some time to populate even though the files may
contain data. The CDH4.1 version of Flume includes FLUME-1238, which
will do auto-rolling of files and helps lower the period where these
files appear to be 0 size.

Since the CDH3u5 version of Flume is compatible with CDH3* Hadoop and
the CDH4 Flume is compatible with CDH4* Hadoop, you can download the
nightly build of flume-ng-1.2.0-cdh4.1.0 from
http://nightly.cloudera.com/cdh4/cdh/4/

Re: HDFS sink leaves .tmp files

Eran Kutner 2012-09-10, 23:15

I'm using flume 1.2 on CDH4:
Flume 1.2.0
Subversion https://svn.apache.org/repos/asf/flume/tags/flume-1.2.0-rc1 -r
1360090
Compiled by mpercy on Wed Jul 11 02:54:24 PDT 2012
>From source with checksum 8eb3085d75407e62436c83fab38c8645

But I think I figured why it's happening. I have multiple flume agents
writing to the same directory. I assumed the annoying number that got
appended to the file names was added to make them unique but it doesn't.
Although it looks like a time stamp it is being incremented sequentially
which means multiple servers are trying to write the same files at the same
time. I think that was causing the problem.
I've now added a hostname interceptor and added the hostname to the file
names to distinguish them and at least for now the problem seems to be gone.

Thanks Kathleen!
I'll download that build tomorrow morning and give it a whirl.

Re: HDFS sink leaves .tmp files

Chris Neal 2012-09-13, 14:38

Just to follow up, the .tmp file problem did go away using 1.3.0-SNAPSHOT
on the HDFS sink agent.

Thanks again Kathleen :)

答复: HDFS sink leaves .tmp files

Shara Shi 2012-11-06, 02:47

I met the similar problem that .tmp file appears on hdfs when hdfs reboot.
I think the file dose not be closed properly . But I don't know how to
handle this problem.

Re: 答复: HDFS sink leaves .tmp files

Kathleen Ting 2012-11-06, 20:05

Hi Shara,

The .tmp file contains the actual data before it is renamed to the
final file. If the .tmp file is still open, then Flume is still
holding it open in order to write to it. If Flume somehow dies and is
unable to clean up the .tmp files, then once the client lease expires,
the NameNode will consider it closed (but the NameNode will not rename
it from .tmp - we recommend writing a script to do that).

Regards, Kathleen
