How to resolve ERROR 4534 which I get during export?

The issue/bug can be related to a mismatch of the buffersize for an export and import which is addressed in V6.0SP2. 

One way to verify that, this was the bug was to run an explain plan query against their db. Issue the following commands 

dbadmin=> \o | grep -i 'buffersize' 
dbadmin=> explain local verbose EXPORT TO VERTICA cig_ssc.monitor.QUERY_REQUESTS as select * from monitor.QUERY_REQUESTS;
dbadmin=> \o 

This should display some information for you.

Check the output for 

2[label = "Export\nExport for BufferSize and then also
3[label = "Import\nImport for Buffersize.

The value for the Buffersize is a mismatch between the export and import.
The solutions is to either apply SP2  on both clusters or to export smaller chunks / selections.

One customer is getting this error when exporting/importing from 6.1.3 to 7.0, does same solution apply?

I am also facing same error on upgrading from 6.1 to 7.0 version

This issue may have to do with network compressions
