Hi,

 

we updated sqoop from cdh5.0.1 to cdh5.2 and now it fails everytime with a GC overhead limit exceeded error.

The old version was able to import over 14GB of data over one mapper and the import fails now when a mapper gets too many rows. I checked a heap dump and the memory was completely used by over 3.5 million rows of data (-Xmx 1700M).

The connector is mysql-jdbc version 5.1.33 and the job imports the data as text file in a have table.

 

Can I avoid this with a setting or is this a bug that should go to jira?

 

Thank you,

Jürgen
