Unable to do a full import from file (ES 1.3.4)

[AtzeDeVries]

Hi,

I'm trying to export the from my es server (about 22GB, 100K documents, 1 index) to a file. The following situations happen.

• If i create a tar.gz it stops after a 2GB file. Importing it results into 4GB elasticsearch data.
• If i create a bulk.gz it creates about 1.8GB of data, importing results to 23GB and only 14K documents
• If i _push from one server to other server it works correctly.

I would like to have all the data in a file, since it is portable.

Command to export:

curl -XPOST 'localhost:9200/_export?path=/data/elasticsearch_export/nda_export.bulk.gz'

The are two clusters. cluster A containg 1 node, and cluster B containing 3 nodes. I'm trying to move data from A to B.

download link of plugin is
http://xbib.org/repository/org/xbib/elasticsearch/plugin/elasticsearch-knapsack/${es_version}.0/elasticsearch-knapsack-${es_version}.0-plugin.zip where $es_version is 1.3.4

I forgot to upload 1.3.4.1 in October. Now it's there. Can you try 1.3.4.1 to check if the problems persist? Thanks.

Hi,

So i've did a lot of testing, but found the solution. The mapping was not transfered (or not correctly transfered) to the new server if you move the data via a file. If i inject the mapping before the _import that it seems to work fine (the export is a bulk.gz of one index).

[jprante]

Yes. The bulk archive is not able to transport mappings. The ES bulk format has no mechanism for creating mappings, only for document indexing.

ok, than stil the issue of 'non' bulk exports only begin 2GB is still
standing. I did not try to export it to a tar file instead of tar.gz. I did
test it to breakup in multipe files, but the total of tar.gz multiple
files was 2GB

Yes, I checked. The fix was not backported.

If you can build form source, here is a quick fix:

Set longFileMode in this line

https://github.com/jprante/elasticsearch-knapsack/blob/1.3/src/main/java/org/xbib/io/archive/tar/TarArchiveOutputStream.java#L84

to LONGFILE_GNU

[AtzeDeVries]

so it is only a problem with tar files? Then could just use .zip which is fine be me. (i can't test at the moment, since the testing server is runnig a different job)/.

[jprante]

Yes, it's a tar format peculiarity, the original tar is limited to 2GB, while POSIX TAR or GNU TAR is not.

[AtzeDeVries]

Ok, then i'll try the zip method tomorrow. I'll report back on that
